DrMu

the Dynamic Route53 MikroTik Updater

Description

This utility creates a webserver, that accepts requests to the URL "/drmu/update/:domainName/:ipAddress"

Where :domainName is the subdomain name (eg. host1.example.com), and :ipAddress is the IP address to point to. Subdomains that don't exist, will be created, and existing ones updated.
