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.
DNS Configuration
Providers
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 will pull from DNS Made Easy servers through AXFR (an automated, 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 be hosted by Dyn servers.
Other details:
- The plan with DNS Made Easy to which we are subscribed is Business Membership, allowing for 25 domains, 3 failover records, and 10 million queries per month (for all domains).
- Secondary service is only enabled for unipharm.com and medicinecentre.com. Though we serve other domains, they are not as important as to justify a second level of redundancy through Dyn (the service cost is per domain).
Domains
The following domains are served by uniPHARM
Technical notes
- Configuration TTL time is currently
