Using AWS/Route53 for Dynamic DNS


Quick view

AWS/Route53 provides a fully featured and configurable DNS service for a reasonable price. This makes it good choice for your Dynamic DNS setup. However Route53 is not yet well supported by the usual DDNS clients. The ddns-updater tool closes this gap.

To use AWS/Route53 for your Dynamic DNS an AWS account is required. Furthermore a hosted zone has to be setup in prior to using the ddns-updater tool (see Route53 documentation for how to do this). The ddns-updater tool is capable to update the A (IPv4) and AAAA (IPv6) records in this hosted zone with your host's current IPv4 and/or IPv6 address.

For example, if the Route53 hosted zone is with configured A and AAAA records for the server name the command line

java -jar ddns-updater-boot-<version> --host

will determine the current IPv4 and IPv6 address of the current host and update the A and AAAA records if they differ. Every 24h the update will be forced anyway to recover from undetected divergences. By applying the --noipv4 or --noipv6 command line option the update can be restricted according to the actual host setup.

See the ddns-updater home page for the full command line description.
