Description: DNS Zone Transfer is generally used for DNS database replications and backups. In this video we will look at how a DNS Zone Transfer can be done using the Dig utility. An interesting point which we will see is that not all DNS servers are configured to allow DNS zone transfers to any public request for a transfer. The DNS Zone transfer is also sometimes symbolized with the opcode mnemonic AXFR, which is the DNS transaction type used to signify a DNS Zone Transfer. Links:<br><br>1. DNS Basics<br><br>2.
