Resetting Your IP With Comcast

P.S. - I don't mean to be a dick, but if you're just going to reply and say "why do you want to change your IP?" then don't respond at all. It's simply out of curiosity.

I've had Comcast for the better part of 10 years. First off you will most likely get someone who has NO IDEA how to change your IP address, thus you need to help them do it ( with out making them feel stupid)


This is what you do. First off the RELEASE/RENEW should work in therory because they tell you that your IP address is not static, well thats a bunch of horse shit.

For NOT being a static ip it sure stays the same when you release and renew right?

What I finaly ended up doing is this.

Call them up, tell them you want an additional IP address. It costs like 5 bucks extra month. Tell them thanks.

Then release and renew , you should get that other IP address they just assigned you. Once you do, call them up and cancel the ip, tell them your other computer had a melt down or something. Most of the time I just told them to cancel it and they did.

Your IP will be change, they will end up canceling the unused IP, and since your using the new one, the old one will get canceled.


Hope this helps.

Jam it back in, in the dark.
