A zone file contains mappings between domain names IP addresses and other resources organized in the form of resource records RR. 5202020 DNS Zone Files and Resource Record Types. The portion of the database that is replicated is known as a zone.
This is how DNS builds its resilience on the Internet. This latter type of DNS transfer takes place when an attacker detects a misconfigured DNS server that is actually responding to AXFR requests. If DNS record is not found in the RPZ then the request will be forwarded to an upstream DNS resolver.
A DNS server hosting a primary zone is normally called a primary name server masterand one hosting a secondary zone is a secondary name server slave. All About the DNS Zone File DNS zone files are defined in RFC 1035 and RFC 1034. If the query is successful all domains and domain types are returned along with common type specific data SOAMXNSPTRA.
