I was hosting a server today when my friend said he could not connect to it over IRC, strangly others were connect, it will see strange nce I get further into the problem. I opened up command prompt, typed in ipconfig, and hit enter. I had forwarded my ports to 192.168.1.100, but today my IPv4 had changed to 192.168.1.103 on it's own :/ I checked recently right now and it has changed again to 192.168.1.102(preferred). Any idea what could be causing this, or is it normal to do this?
