ChangeIP.com Domain Names and Dynamic DNS Services
These are a great bunch of guys and have always provided flawless DNS and Domain Name services for all the domains I manage.
They’re always available for first-class tech support, say what they do, and do what they say.
And even better than all that, they’ve never screwed me over like “other registrars” have done to various people, by stealing domains as they expire and trying to sell them back, or locking your domain so you can’t transfer it away.
ChangIP is the FedEx of DNS providers. They do exactly what they say they do and you don’t need to worry about “what happens now?”
