Do you only support certain TLD (top level domains)?

Hosted DNS
We have no restrictions. We support every TLD currently in existence, and even those that don't exist yet. We also have name servers with the extensions of .com, .net, .info, .org, .co.uk and more to make it easy to match up a name server TLD to your domains' TLD to ensure a speedy resolution. Not many providers go through the expense of doing that.
