I assumed nslookup would either error when looking up non internet names or would give the correct answer but I'm confused by the following behaviour. Have I misunderstood how to use it or its output/limitations?

$ resolveip raspberrypi.local IP address of raspberrypi.local is 192.168.0.41 $ nslookup raspberrypi.local Server: 194.168.4.100 Address: 194.168.4.100#53 ** server can't find raspberrypi.local: NXDOMAIN

The answer of 192.168.0.41 from resolveip is correct but the nslookup answer is not correct. Also I'm wondering what the #53 part of the address is referring to. Surely it's not port number. The man page for nslookup doesn't seem to explain it.

The behavior of resolveip vs nslookup was already discussed a little here already but it seems resolveip will check hosts and then move on to DNS checks while nslookup will go straight to DNS. So I would assume that it knows the pi from either the hosts file or from the local network via some other means (arp?), it seems that the pi is not registered with your DNS server.

Also the #53 refers to the port that responded from the server. See this discussion.
