Let's talk about
nslookup, a fantastic program that I use with funceble to get information about domain(s).
nslookup is a program that will help us or a sysadmin find out the corresponding IP address of a domain name.
It can also give us the host name for an IP address.
Let's try to get the information about funilrys.com
Valid domain name
$ nslookup funilrys.com Server: 192.168.178.1 Address: 192.168.178.1#53 Non-authoritative answer: Name: funilrys.com Address: 220.127.116.11 Name: funilrys.com Address: 2001:8d8:100f:f000::22e
Invalid domain name
$ nslookup funilrys.comm Server: 192.168.178.1 Address: 192.168.178.1#53 ** server can't find funilrys.comm: NXDOMAIN
This is pretty useful if we want to know if a domain is still active or not.
It's the domain name.
It's the corresponding IP (IPv6 and IPv4) address of the domain name.
