nslookup looks *only* in DNS. If you want a tool that follows the same hostname lookup policies that programs like "ping" use, there's getent(1). hobbit:~$ nslookup hobbit Server: 127.0.0.1 Address: 127.0.0.1#53 ** server can't find hobbit: NXDOMAIN hobbit:~$ getent hosts hobbit 127.0.1.1 hobbit.wooledge.org hobbit hobbit:~$ getent hosts www.debian.org 2603:400a:ffff:bb8::801f:3e www.debian.org Of course, a lot of people just use "ping" for this same purpose. It's not ideal, but it works. hobbit:~$ ping -c1 hobbit PING hobbit.wooledge.org (127.0.1.1) 56(84) bytes of data. 64 bytes from hobbit.wooledge.org (127.0.1.1): icmp_seq=1 ttl=64 time=0.015 ms --- hobbit.wooledge.org ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.015/0.015/0.015/0.000 ms
