As an starting point you should read "The Tao of the IETF" RFC4677 (currently, update draft in progress).
About your particular question read section 8.4.5.

Right. And it's subtler than you think. Some network operators have patents (not just vendors). Some are held by organizations that only exist to hold patents and don't actually know much about networking. And just because something is patented doesn't mean it isn't interoperable -- most networking standards are patented.
Just like as - "US Patent 6701329 - Aging and scavenging of DNS resource records" (Microsoft) - "US Patent 7337910 - Methods and devices for responding to request for unregistered domain name to indicate a predefined type of service" (Verisign SiteFinder fiasco) - "US Patent 6560634 - Method of determining unavailability of an internet domain name" (Verisign) - "US Patent 7580982 - Email filtering system and method" (Go Daddy) - "US Patent 7130878 - Systems and methods for domain name registration by proxy" (Go Daddy) Just to list a few. Be careful the next time you use "vi", somebody may have already patented that regular expression. Cheers Jorge
