Anyone want to use my new root DNS server ?
It'll have all the same zone records for all the TLDs you are used to, but none of the new ones sold to organisations which represent no wider Internet community. How to pay for it ? Oh I guess I could include a paid for advert whenever I get a hit on a TLD which isn't a known trademark, and state my policy not to resolve it whenever I get a hit on a TLD which is a known trademark. Guess I'd get too much interest from hostile lawyers otherwise.
Some users might find this more secure, as it will never resolve internal single label names to external addresses.
Copyright infringement suit from ICANN ? Well maybe, but I guess I could locate the business somewhere with sensible copyright precedents where well known public knowledge doesn't belong to anyone.
