Description

Referrals (parent side NS RRset at zone cut) and glue are important. However, the importance is not well described in DNS standards. RFC 2181 Section 5.4.1 "Ranking data" shows that referrals ranking is lowest. However, the referrals make zones and specify name servers that serve authoritative data for the zones. The glue specifies IP addresses of the name servers that serve authoritative data for the zone. The NS RRset at the apex of the zone is authoritative data, however, it does not make the zone cut. NS RRset at parent side is more important than NS RRSet at child side. This presentation will explain the details, propose clarifications of DNS standards and new name resolution method, and report an experiment/simulation result of new name resolution algorithm. Proposed name resolution method use referrals, glue and out-of-bailiwick name server information to iterate DNS tree and responds authoritative data only (except referrals and glue).
