IP without being on a network?

Is there anyway to emulate a network connection?

Here is what I am trying to do.

I have a license service running on my computer. The software that looks for the license service requires an IP address. When I am on my home network I have my internal IP set static to 192.168.1.110, so it all works fine. If I wanted to take my laptop to say the pub and do some work without a network connection, I would not be able to use my software as it can't find itself at 192.168.1.110 as it hasn't assigned an IP as it's not on a network..

Hope somebody can understand what I am trying to get at

You could use 127.0.0.1 as a local loopback address or you could assign yourself a static 192.168.1.x address.

ahhhhh Thats clever! I'll give it a test on my spare PC that isn't on the network. That will be perfect if it works. Thanks a bunch

Is this set statically? or is it set via the router?

Set it statically on the machine, may need to set itself as the DNS/gateway. Have a play until you can ping the IP without the router.

Once it's sorted, you could have a bat flie for switching between the two settings.

I set the router so it only assigns between .2 to .99, so it can never assign anything with .100 or more stopping any IP's getting doubled up. Then I set things like my PC, server etc static via each device on the network adapter settings.

Actually, thinking about it some more, you may need to install the loop back network adaptor (if such a thing still exists in the latest windows) or you can make a loopback rj45 plug that would let the network port think it was connected.
