It typically includes the IP address(es) associated with the domain name, as well as additional information such as the DNS server used for the lookup.If you want to perform a reverse DNS lookup (finding the domain name associated with an IP address), you can provide the IP address instead of the domain name:
nslookup {{IP address}}
