iPAddress property
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
.
IPAddress
. This ensures that the IP address of your
instance will never change.
For more information, see FullyQualifiedDomainName.
Constraints: Route 53 can't check the health of endpoints for which the IP address is in local, private, non-routable, or multicast ranges. For more information about IP addresses for which you can't create health checks, see the following documents:
- RFC 5735, Special Use IPv4 Addresses
- RFC 6598, IANA-Reserved IPv4 Prefix for Shared Address Space
- RFC 5156, Special-Use IPv6 Addresses
