You will need to give some more details on your setup and what you are trying to do. For example, are you running a server? What version of Linux? What applications being used? .....etc.

One good thing to know is "man -k <keyword>" In your case try "man -k network" or "man -k host"

You can always ping the IP and see if you get a reply back as most servers/workstations allow ICMP requests. In case they don't allow that, look up how to use nmap.
