DNS zone transfer dump

SkyHi @ Wednesday, June 20, 2012
DNS zone transfer, also sometimes known by its (most common) opcode mnemonic AXFR, is a type of DNS transaction. It is one of the many mechanisms available for administrators to replicate DNS databases across a set of DNS servers. Zone transfer comes in two flavors, full (opcode AXFR) and incremental (IXFR). Nearly universal at one time, it is now becoming less popular in favor of the use of other database replication mechanisms that modern DNS server packages provide.
