Re: Find out if an IP address is in use on the LAN

Gonna let Wireshark run for about 30 minutes to see if anything shows up.

Thanks.

I've pinged it and get no reply, but some things don't reply to a ping,

do

they? Or because I used an actual IP address in the ping, is that a
definitive answer that it's not in use because I got no reply?

No, it's not definitive. Some devices deliberately don't answer ping.
It could also be rebooting, sleeping, powered off or showing the Blue
Screen of Death.

Is there a way? I'm on Windows 7.

I'd use Wireshark. Run it for a while and capture anything coming/going
to that IP address.
