NameCheap FreeDNS and .is Domains
One more NameCheap-related article. Yeah, I'm a big fan of their services!
TL;DR: FreeDNS can't manage .is domains.
For some client work, I needed to use NameCheap's FreeDNS service to manage a domain name with the .is extension.
After some back and fourth with the domain registrar to try and switch the DNS to FreeDNS, I finally got in touch with NameCheap's support team and started what ended up being a 1-hour conversation on their live chat.
By investigating the issue bits by bits, we came to the conclusion that FreeDNS can't manage .is domain names because it doesn't fit the .is registry requirements.
The part that blocks everything is that FreeDNS's nameservers' TTL is set to 1800 seconds while the .is registry requires at least 86400 seconds. The NS's TTL can't be changed, even internally by the NameCheap's team.
So, sadly, a .is domain name can't be managed by NameCheap :(
