Information Systems:Migration to externally-hosted DNS service

This page will either remain a project page (in which case it should be marked to be archived), or will become a meta page for DNS configuration. 

Overview

Project date: Mar. 2017

It has been decided that DNS hosting will be migrated from on-site hosting using Infoblox appliances to third-party DNS hosting providers. This configuration will be tried for a year, after which the solution will be reassessed.

Configuration

There will be two hosting providers:

• Primary: DNS Made Easy (username/password found here)
• Secondary: Dyn.com (DynDNS) (username/password found here)

It is important to note that service with Dyn.com is purely secondary DNS, and thus records cannot be managed there. Rather, Dyn servers pull from DNS Made Easy servers through AXFR (a background mechanism requiring configuration at both providers). Any changes made to DNS Made Easy servers will eventually be mirrored onto Dyn servers through periodic NOTIFY syncs, after which those records will begin to also be hosted by Dyn servers.
