Explanation

A DNS zone transfer is a process where the DNS records (which make up the zone file) are copied from the primary DNS server (also called the master) to a secondary DNS server (slave). This ensures that the DNS records are consistent across multiple DNS servers, providing redundancy and load balancing for DNS queries. Zone transfers can be either full (AXFR) or incremental (IXFR), where the latter only transfers the changed records instead of the entire zone file.
