Explanation

AXFR (full zone transfer) and IXFR (incremental zone transfer) are DNS record types used to replicate zone data between DNS servers. When an attacker uses DIG to request an AXFR or IXFR, they are attempting a DNS zone transfer - pulling a complete copy of the DNS zone file. This reveals all hostnames, IP addresses, mail servers, and subdomains registered in the zone, giving the attacker a detailed internal network map for further attack planning.
