zone transfer

A zone transfer is a process used in internet domain management where a primary DNS server shares its database of domain information with a secondary DNS server. This typically happens to ensure the secondary server has an updated copy of the domain’s records, such as IP addresses and mail servers. Think of it like updating a backup copy of important contact details, so if the primary source goes offline, the secondary can continue providing accurate information. Proper security measures are essential during zone transfers to prevent unauthorized access.
