For this challenge, your goal is to perform a zone transfer on the internal zone named: "int" using the nameserver of z.hackycorp.com.
ZONE TRANSFER
Zone transfers are usually used to synchronize multiple DNS servers. Only a list of pre-defined hosts should be able to perform this operation. However, it's sometimes possible to retrieve information from internal zones by asking publicly available servers.
SOLUTION
digAXFR@z.hackycorp.comint
dig: The tool for querying DNS.
AXFR: The query type, which requests a zone transfer (a copy of all DNS records for a domain).
@z.hackycorp.com: Specifies the DNS server (z.hackycorp.com) to contact.
int: The domain (zone) you're requesting the transfer for, in this case, int.
