	// distribution. You can get the value of DnsName using the AWS CLI command
	// describe-vpc-endpoints (https://docs.aws.amazon.com/cli/latest/reference/ec2/describe-vpc-endpoints.html).
	//

	// Specify the domain name that CloudFront assigned when you created your distribution.
	//
	// Your CloudFront distribution must include an alternate domain name that matches
	// the name of the resource record set. For example, if the name of the resource
	// record set is acme.example.com, your CloudFront distribution must include
	// acme.example.com as one of the alternate domain names. For more information,
	// see Using Alternate Domain Names (CNAMEs) (https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/CNAMEs.html)
	// in the Amazon CloudFront Developer Guide.
	//
	// You can't create a resource record set in a private hosted zone to route

	//
	// For failover alias records, you can't specify a CloudFront distribution for

	// domain name in more than one distribution.
	//
	// Elastic Beanstalk environment
	//
	// If the domain name for your Elastic Beanstalk environment includes the region
	// that you deployed the environment in, you can create an alias record that
	// routes traffic to the environment. For example, the domain name my-environment.us-west-2.elasticbeanstalk.com
	// is a regionalized domain name.
	//
	// For environments that were created before early 2016, the domain name doesn't
	// include the region. To route traffic to these environments, you must create
	// a CNAME record instead of an alias record. Note that you can't create a CNAME
	// record for the root domain name. For example, if your domain name is example.com,
	// you can create a record that routes traffic for acme.example.com to your
	// Elastic Beanstalk environment, but you can't create a record that routes
	// traffic for example.com to your Elastic Beanstalk environment.
	//
	// For Elastic Beanstalk environments that have regionalized subdomains, specify
	// the CNAME attribute for the environment. You can use the following methods
	// to get the value of the CNAME attribute:
	//
	//    * AWS Management Console: For information about how to get the value by
	//    using the console, see Using Custom Domains with AWS Elastic Beanstalk
	//    (https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/customdomains.html)
	//    in the AWS Elastic Beanstalk Developer Guide.
	//
	//    * Elastic Beanstalk API: Use the DescribeEnvironments action to get the
	//    value of the CNAME attribute. For more information, see DescribeEnvironments
	//    (https://docs.aws.amazon.com/elasticbeanstalk/latest/api/API_DescribeEnvironments.html)
	//    in the AWS Elastic Beanstalk API Reference.
	//
	//    * AWS CLI: Use the describe-environments command to get the value of the
	//    CNAME attribute. For more information, see describe-environments (https://docs.aws.amazon.com/cli/latest/reference/elasticbeanstalk/describe-environments.html)
	//    in the AWS CLI Command Reference.
	//
	// ELB load balancer
	//
	// Specify the DNS name that is associated with the load balancer. Get the DNS
	// name by using the AWS Management Console, the ELB API, or the AWS CLI.
	//
	//    * AWS Management Console: Go to the EC2 page, choose Load Balancers in
	//    the navigation pane, choose the load balancer, choose the Description
	//    tab, and get the value of the DNS name field. If you're routing traffic
	//    to a Classic Load Balancer, get the value that begins with dualstack.
	//    If you're routing traffic to another type of load balancer, get the value
	//    that applies to the record type, A or AAAA.
	//
	//    * Elastic Load Balancing API: Use DescribeLoadBalancers to get the value
	//    of DNSName. For more information, see the applicable guide: Classic Load
	//    Balancers: DescribeLoadBalancers (https://docs.aws.amazon.com/elasticloadbalancing/2012-06-01/APIReference/API_DescribeLoadBalancers.html)
	//    Application and Network Load Balancers: DescribeLoadBalancers (https://docs.aws.amazon.com/elasticloadbalancing/latest/APIReference/API_DescribeLoadBalancers.html)

	//
	// Specify the domain name of the Amazon S3 website endpoint that you created

	// information about valid values, see the table Amazon S3 Website Endpoints
	// (https://docs.aws.amazon.com/general/latest/gr/s3.html#s3_website_region_endpoints)
	// in the Amazon Web Services General Reference. For more information about

	//
	// Another Route 53 resource record set
	//
	// Specify the value of the Name element for a resource record set in the current
	// hosted zone.
	//
	// If you're creating an alias record that has the same name as the hosted zone
	// (known as the zone apex), you can't specify the domain name for a record
	// for which the value of Type is CNAME. This is because the alias record must
	// have the same type as the record that you're routing traffic to, and creating
	// a CNAME record for the zone apex isn't supported even for an alias record.
	//
	// DNSName is a required field
	DNSName *string `type:"string" required:"true"`

	// Applies only to alias, failover alias, geolocation alias, latency alias,
	// and weighted alias resource record sets: When EvaluateTargetHealth is true,
	// an alias resource record set inherits the health of the referenced AWS resource,
	// such as an ELB load balancer or another resource record set in the hosted
	// zone.
	//
	// Note the following:
	//
	// CloudFront distributions
	//
	// You can't set EvaluateTargetHealth to true when the alias target is a CloudFront
	// distribution.
	//
	// Elastic Beanstalk environments that have regionalized subdomains
	//
	// If you specify an Elastic Beanstalk environment in DNSName and the environment
	// contains an ELB load balancer, Elastic Load Balancing routes queries only
	// to the healthy Amazon EC2 instances that are registered with the load balancer.
	// (An environment automatically contains an ELB load balancer if it includes
	// more than one Amazon EC2 instance.) If you set EvaluateTargetHealth to true
	// and either no Amazon EC2 instances are healthy or the load balancer itself
	// is unhealthy, Route 53 routes queries to other available resources that are
	// healthy, if any.
	//
	// If the environment contains a single Amazon EC2 instance, there are no special
	// requirements.
	//
	// ELB load balancers
	//
	// Health checking behavior depends on the type of load balancer:
	//
	//    * Classic Load Balancers: If you specify an ELB Classic Load Balancer
	//    in DNSName, Elastic Load Balancing routes queries only to the healthy
	//    Amazon EC2 instances that are registered with the load balancer. If you
	//    set EvaluateTargetHealth to true and either no EC2 instances are healthy
	//    or the load balancer itself is unhealthy, Route 53 routes queries to other
	//    resources.
	//
	//    * Application and Network Load Balancers: If you specify an ELB Application
	//    or Network Load Balancer and you set EvaluateTargetHealth to true, Route
	//    53 routes queries to the load balancer based on the health of the target
	//    groups that are associated with the load balancer: For an Application
	//    or Network Load Balancer to be considered healthy, every target group
	//    that contains targets must contain at least one healthy target. If any
	//    target group contains only unhealthy targets, the load balancer is considered
	//    unhealthy, and Route 53 routes queries to other resources. A target group
	//    that has no registered targets is considered unhealthy.
	//
	// When you create a load balancer, you configure settings for Elastic Load
	// Balancing health checks; they're not Route 53 health checks, but they perform
	// a similar function. Do not create Route 53 health checks for the EC2 instances
	// that you register with an ELB load balancer.
	//
	// S3 buckets
	//
	// There are no special requirements for setting EvaluateTargetHealth to true
	// when the alias target is an S3 bucket.
	//
	// Other records in the same hosted zone
	//
	// If the AWS resource that you specify in DNSName is a record or a group of
	// records (for example, a group of weighted records) but is not another alias
	// record, we recommend that you associate a health check with all of the records
	// in the alias target. For more information, see What Happens When You Omit
	// Health Checks? (https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/dns-failover-complex-configs.html#dns-failover-complex-configs-hc-omitting)

	// address and passes the value of FullyQualifiedDomainName in the Host header
	// for all health checks except TCP health checks. This is typically the fully
	// qualified DNS name of the endpoint on which you want Route 53 to perform
	// health checks.
	//
	// When Route 53 checks the health of an endpoint, here is how it constructs
	// the Host header:
	//
	//    * If you specify a value of 80 for Port and HTTP or HTTP_STR_MATCH for
	//    Type, Route 53 passes the value of FullyQualifiedDomainName to the endpoint
	//    in the Host header.
	//
	//    * If you specify a value of 443 for Port and HTTPS or HTTPS_STR_MATCH
	//    for Type, Route 53 passes the value of FullyQualifiedDomainName to the
	//    endpoint in the Host header.
	//
	//    * If you specify another value for Port and any value except TCP for Type,
	//    Route 53 passes FullyQualifiedDomainName:Port to the endpoint in the Host
	//    header.
	//
	// If you don't specify a value for FullyQualifiedDomainName, Route 53 substitutes
	// the value of IPAddress in the Host header in each of the preceding cases.
	//
	// If you don't specify a value for IPAddress :
	//
	// Route 53 sends a DNS request to the domain that you specify for FullyQualifiedDomainName
	// at the interval that you specify for RequestInterval. Using an IPv4 address
	// that DNS returns, Route 53 then checks the health of the endpoint.
	//
	// If you don't specify a value for IPAddress, Route 53 uses only IPv4 to send
	// health checks to the endpoint. If there's no resource record set with a type
	// of A for the name that you specify for FullyQualifiedDomainName, the health
	// check fails with a "DNS resolution failed" error.
	//
	// If you want to check the health of weighted, latency, or failover resource
	// record sets and you choose to specify the endpoint only by FullyQualifiedDomainName,
	// we recommend that you create a separate health check for each endpoint. For
	// example, create a health check for each HTTP server that is serving content
	// for www.example.com. For the value of FullyQualifiedDomainName, specify the
	// domain name of the server (such as us-east-2-www.example.com), not the name
	// of the resource record sets (www.example.com).
	//
	// In this configuration, if you create a health check for which the value of
	// FullyQualifiedDomainName matches the name of the resource record sets and
	// you then associate the health check with those resource record sets, health
	// check results will be unpredictable.
	//
	// In addition, if the value that you specify for Type is HTTP, HTTPS, HTTP_STR_MATCH,
	// or HTTPS_STR_MATCH, Route 53 passes the value of FullyQualifiedDomainName
	// in the Host header, as it does when you specify a value for IPAddress. If

	// The IPv4 or IPv6 IP address of the endpoint that you want Amazon Route 53
	// to perform health checks on. If you don't specify a value for IPAddress,
	// Route 53 sends a DNS request to resolve the domain name that you specify
	// in FullyQualifiedDomainName at the interval that you specify in RequestInterval.
	// Using an IP address returned by DNS, Route 53 then checks the health of the
	// endpoint.
	//
	// Use one of the following formats for the value of IPAddress:
	//
	//    * IPv4 address: four values between 0 and 255, separated by periods (.),
	//    for example, 192.0.2.44.
	//
	//    * IPv6 address: eight groups of four hexadecimal values, separated by
	//    colons (:), for example, 2001:0db8:85a3:0000:0000:abcd:0001:2345. You
	//    can also shorten IPv6 addresses as described in RFC 5952, for example,
	//    2001:db8:85a3::abcd:1:2345.
	//
	// If the endpoint is an EC2 instance, we recommend that you create an Elastic
	// IP address, associate it with your EC2 instance, and specify the Elastic
	// IP address for IPAddress. This ensures that the IP address of your instance

	//    * CLOUDWATCH_METRIC: The health check is associated with a CloudWatch
	//    alarm. If the state of the alarm is OK, the health check is considered
	//    healthy. If the state is ALARM, the health check is considered unhealthy.
	//    If CloudWatch doesn't have sufficient data to determine whether the state
	//    is OK or ALARM, the health check status depends on the setting for InsufficientDataHealthStatus:

	// set with a Type of A and a ContinentCode of AF.
	//
	// Although creating geolocation and geolocation alias resource record sets
	// in a private hosted zone is allowed, it's not supported.
	//
	// If you create separate resource record sets for overlapping geographic regions
	// (for example, one resource record set for a continent and one for a country
	// on the same continent), priority goes to the smallest geographic region.
	// This allows you to route most queries for a continent to one resource and

	//
	// Route 53 doesn't check the health of the endpoint that is specified in the
	// resource record set, for example, the endpoint specified by the IP address

	//
	// When to Specify HealthCheckId
	//
	// Specifying a value for HealthCheckId is useful only when Route 53 is choosing
	// between two or more resource record sets to respond to a DNS query, and you
	// want Route 53 to base the choice in part on the status of a health check.
	// Configuring health checks makes sense only in the following configurations:
	//
	//    * Non-alias resource record sets: You're checking the health of a group
	//    of non-alias resource record sets that have the same routing policy, name,
	//    and type (such as multiple weighted records named www.example.com with
	//    a type of A) and you specify health check IDs for all the resource record
	//    sets. If the health check status for a resource record set is healthy,
	//    Route 53 includes the record among the records that it responds to DNS
	//    queries with. If the health check status for a resource record set is
	//    unhealthy, Route 53 stops responding to DNS queries using the value for
	//    that resource record set. If the health check status for all resource
	//    record sets in the group is unhealthy, Route 53 considers all resource
	//    record sets in the group healthy and responds to DNS queries accordingly.
	//
	//    * Alias resource record sets: You specify the following settings: You
	//    set EvaluateTargetHealth to true for an alias resource record set in a
	//    group of resource record sets that have the same routing policy, name,
	//    and type (such as multiple weighted records named www.example.com with
	//    a type of A). You configure the alias resource record set to route traffic
	//    to a non-alias resource record set in the same hosted zone. You specify
	//    a health check ID for the non-alias resource record set. If the health
	//    check status is healthy, Route 53 considers the alias resource record
	//    set to be healthy and includes the alias record among the records that
	//    it responds to DNS queries with. If the health check status is unhealthy,
	//    Route 53 stops responding to DNS queries using the alias resource record
	//    set. The alias resource record set can also route traffic to a group of
	//    non-alias resource record sets that have the same routing policy, name,
	//    and type. In that configuration, associate health checks with all of the
	//    resource record sets in the group of non-alias resource record sets.
	//
	// Geolocation Routing
	//
	// For geolocation resource record sets, if an endpoint is unhealthy, Route
	// 53 looks for a resource record set for the larger, associated geographic
	// region. For example, suppose you have resource record sets for a state in
	// the United States, for the entire United States, for North America, and a
	// resource record set that has * for CountryCode is *, which applies to all
	// locations. If the endpoint for the state resource record set is unhealthy,
	// Route 53 checks for healthy resource record sets in the following order until
	// it finds a resource record set for which the endpoint is healthy:
	//
	//    * The United States
	//
	//    * North America
	//
	//    * The default resource record set
	//
	// Specifying the Health Check Endpoint by Domain Name
	//
	// If your health checks specify the endpoint only by domain name, we recommend
	// that you create a separate health check for each endpoint. For example, create
	// a health check for each HTTP server that is serving content for www.example.com.
	// For the value of FullyQualifiedDomainName, specify the domain name of the
	// server (such as us-east-2-www.example.com), not the name of the resource
	// record sets (www.example.com).
	//
	// Health check results will be unpredictable if you do the following:
	//
	//    * Create a health check that has the same value for FullyQualifiedDomainName
	//    as the name of a resource record set.
	//
	//    * Associate that health check with the resource record set.
	HealthCheckId *string `type:"string"`

	// Multivalue answer resource record sets only: To route traffic approximately
	// randomly to multiple resources, such as web servers, create one multivalue
	// answer record for each resource and specify true for MultiValueAnswer. Note
	// the following:
	//
	//    * If you associate a health check with a multivalue answer resource record
	//    set, Amazon Route 53 responds to DNS queries with the corresponding IP
	//    address only when the health check is healthy.
	//
	//    * If you don't associate a health check with a multivalue answer record,
	//    Route 53 always considers the record to be healthy.
	//
	//    * Route 53 responds to DNS queries with up to eight healthy records; if
	//    you have eight or fewer healthy records, Route 53 responds to all DNS
	//    queries with all the healthy records.
	//
	//    * If you have more than eight healthy records, Route 53 responds to different
	//    DNS resolvers with different combinations of healthy records.
	//
	//    * When all records are unhealthy, Route 53 responds to DNS queries with
	//    up to eight unhealthy records.
	//
	//    * If a resource becomes unavailable after a resolver caches a response,
	//    client software typically tries another of the IP addresses in the response.
