tcp/zonetransfer not working reliably is no longer a problem
TCP is a MUST for DNS. It's used as a fallback in the normal resolution process if an answer can't fit in a UDP packet for whatever reason. This is true even for common things like large A record lists, but is only becoming more frequent in the age of DNSSEC, AAAA, etc. It is unfortunately even more necessary than we had hoped it would be due to many local network operators not "getting the memo" regarding EDNS. hth, Doug -- Improve the effectiveness of your Internet presence with a domain name makeover! http://SupersetSolutions.com/ Computers are useless.
