> in addition nowhere does it state in RFC2870 that the root-servers have to > accept AXFR's as part of their service. in fact, the opposite 2.7 Root servers SHOULD NOT answer AXFR, or other zone transfer, queries from clients other than other root servers. This restriction is intended to, among other things, prevent unnecessary load on the root servers as advice has been heard such as "To avoid having a corruptible cache, make your server a stealth secondary for the root zone." The root servers MAY put the root zone up for ftp or other access on one or more less critical servers. randy
