I'm trying to resolve the hostname of devices connected to my wireless lan network through their ip addresses. I'm using a macbook and my /etc/resolv.conf show this as my dns server (192.168.1.1) which is a wireless router

#This file is automatically generated.  
#nameserver 192.168.1.1

i'm trying to find the hostname of the clients connected to my network using their IPs and i'm getting the following error

# nslookup 192.168.1.4 192.168.1.1  
Server: 192.168.1.1  
Address: 192.168.1.1#53  
# server can't find 4.1.168.192.in-addr.arpa.: NXDOMAIN

# nslookup 192.168.1.1  
Server: 192.168.1.1  
Address: 192.168.1.1#53  
server can't find 1.1.168.192.in-addr.arpa.: NXDOMAIN

  • Your router should provide a reverse resolution and make DHCP update that reverse zone, and probably it's not doing it. Unless you can configure your router to update the reverse zone for 192.168.1.0/24 (1.168.192.in-addr.arpa) with DHCP there's no easy way to achieve that. – Pablo Martinez Mar 10 '17 at 18:52

It's almost a certainty that your router does not host a reverse lookup zone, which is required to resolve ip addresses to host names.

If you want or need reverse lookup resolution you'll need to deploy your own internal DNS server.
