Suggested article: DNS zone transfer and zone file

DNS zone transfer is a process of copying the information from the Primary DNS server to the Secondary server or servers. It could be initiated for several recent DNS records or for the entire zone file.

There are two ways for the DNS zone transfer to be done:

• By pushing the update from the Primary DNS server to the Secondary servers.
• By pulling from the Secondary servers to receive the latest changes.

DNS Zone Transfer is required for:

• Set up recently added Secondary DNS servers.
• Every zone file at each DNS server has to be up to date to answer queries adequately.
• Updating DNS records manually at every DNS server is time-consuming.
