The website Domain Daily provides a list of new domain names.
I have a client who would like to implement similar functionality in-house, for semi-real-time tracking of new registrations, but doesn't know how to go about it.
Instinctively, I'd be thinking some sort of service interacting with DNS, WHOIS, or maybe even becoming an official domain name registrar.
Any ideas?
The only reliable way to do this would be to strike a deal with registrys for the TLDs you're interested in (e.g. Verisign (.com), Nominet (.co.uk) etc) and get regular copies of the zone files. They dont tend to make this kind of thing widely avaible though! TLDs like .aero give it away for free however.
