You can use dig followed by a domain name to find one of the IP's that is linked to a certain name. You can also use nslookup. Use man dig or man nslookup for more information about the commands.

A tool like wireshark can help you find out what IPs your computer is communicating with.

Other options:
Use ifconfig to find your ip addr & mask, then use an ip calculator eg http://www.jodies.de/ipcalc to see what addresses are in your range.
You could then use ping in a loop or even nmap to check, BUT unless you are the network admin or know him well, be aware that scanning a net looks like an attack.. YHBW...

The title of this thread is Problem with ip addresses and you are not asking a question about a specific IP address problem. Your statements implying that you are targeting anyone public or private seem unclear as to their meaning.

I do appreciate the correct and helpful answers from Superspeed500 and chrism01. Meanwhile, I have to agree with AwesomeMachine and therefore reiterate their question:

What is your ultimate goal here? Noting also that there are some clear guidelines in the LQ Rules about certain content within thread discussions.

OP just expand & define "foot printing".

Is it allowed here in LQ? LOL.

For this reason, I'm out. (Shark Tank)
