Hi I’m confused with the fact than the number of root servers is limited to 13. >From RFC 3226:
"The current number of root servers is limited to 13 as that is the maximum number of name servers and their address records that fit in one 512-octet answer for a SOA record. If root servers start advertising A6 or KEY records then the answer for the root NS records will not fit in a single 512-octet DNS message, resulting in a large number of TCP query connections to the root servers." A query send to one of the root servers with a long name (length 255) shows that the answer is 511 bytes, returning one A and 13 NS records. My question is: Why are all 13 NS returned?
