Loophole found in Internet Domain Naming

kyndig writes "Just what is the 'spirit of internet naming?' ICANN can tell you, as they are the naming experts. In a recent CNN article, ICANN states EnCirca Domain Register is violating the spirit of internet naming by reselling .pro names. The report states that in early 2000, ICANN allowed 3rd level domains (foo.bar.pro) to be sold. Later, ICANN allowed 2nd level domains (foo.pro) to be sold for .pro as well. The restriction to this selling was that a user must have the 3rd level domain first. There are no reseller checks or usage enforcement other than the request to own a 3rd level domain from ICANN. EnCirca president plans to continue reselling 2nd level .pro domains, unless ICANN places a restriction on doing so."

The reason for a limited number of top level domains is that top level domain lookups require an access to the root DNS servers. There are a relatively small number of theses, and each DNS cache must know the IP addresses of them in order to function. With a small number of TLDs, most domain name lookups can cache the authoritative servers for them. When you look up a .com address, your DNS cache generally already knows where the authoritative server for .com domains is, and so it doesn't need to hit the root servers.

This removes a single point of failure from the domain name system - every single root domain server can fail, and most people will only notice when they enter a TLD which doesn't exist (at which point they will get a DNS failure instead of an nonexistend domain error). Similarly, if the .com servers failed, then you would still be able to access .org domains (for example).
