DNS (53)

Dig

dig axfr <domain> @<ip address>

AXFR (Full Zone Transfer) is a type of DNS zone transfer that replicates the entire DNS zone from the master server to the slave server. This is done when the slave server is being set up or when the master server has been updated with new DNS resource records.

dig axfr realcorp.htb @10.10.10.224
