Answer

There are several types, including:

  • Primary zone: A primary zone is a read/write zone that is stored in a master DNS server.

  • Secondary zone: A secondary zone is a read-only copy of a primary zone that is stored in a slave DNS server.

  • Stub zone: A stub zone is a type of zone that contains only the essential information about a domain name. It is used to reduce the amount of DNS traffic and improve the efficiency of the DNS resolution process.
