Suppose that there are some hosts and one server in the same network that has DNS server running. Also suppose that there is no knowledge of what domain name (or hostname, you can say) is.

By using only IP address, is there any way I can use to figure out what domain name hosts use?

ping -a

will return the hostname, as well as the ping results


will return the nameserver the IP is using and the hostname

Also, you could nslookup your own IP address. If this is a Windows system, ipconfig also gives you this information.
