The AXFR (Asynchronous Full Transfer Zone, or zone transfer) is used to
synchronize the DNS entries for a domain between authoritative name
servers. An AXFR query is usually only approved if it is from the
respective secondary DNS server to the primary DNS server. If there is a
mistake in the configuration of the DNS server, an AXFR query can
nevertheless still be made from any arbitrary IP address.

Attackers take advantage of this problem to obtain information from
systems that are connected to that domain. Then, from this information,
they identify other potential places where they could attack.
