dyndns-aws

This tool updates the specified AWS Route53 record with the external IP address of the host running it, similarly to a dyndns updater.

The external IP address is obtained using the WhatIsMyIP.com API.

If you use tailscale, see tools/tailscale-updater to update your DNS records. This assumes you are using your own DNS servers instead of MagicDNS, more information at https://tailscale.com/kb/1054/dns .

The Route53 credentials are read from ~/.aws/credentials as documented at https://docs.aws.amazon.com/sdk-for-go/v1/developer-guide/configuring-sdk.html .
