Script: Update Linode DNS Records with WAN IPs (Dynamic DNS)

Mon, 27 Nov 2017 10:30:24 -0500

Either of these scripts will grab both the IPv4 and IPv6 (if any) addresses assigned to any WAN I’m behind, and, using Linode’s DNS API, will update my DNS records with same and log changes/errors using logger. In effect, it’s a homemade Dynamic DNS updater. Linode’s developing a new API so that’s why two versions exist.

To use the script, you need:

A Linode API key (for version 3 of Linode’s DNS API) or Personal Access Token (for version 4 of Linode’s DNS API),
the domain ID, and
the resource (called record in v4) IDs of the DNS records you want to update.

The IDs don’t change, whether you’re using version 3 or version 4.
