Will a new Modem force my ISP to give new subnet IP?

[dcyphure]

If i got a new cable modem, i'd have to call comcast isp and tell them i have a new one. Would they assign me a completely new IP..subnet and all?
This would circumvent any kind of forum ban right?

i know i could call and ask for new subnet but they ask alot of questions and then never seem to understand anything technical, they give new IP but same subnet cause i dunno, they dont get it i guess nor am i going to say its to avoid a re-ban ...plus my modem is very old and sometimes cuts out but it is not comcasts modem, i got my own when i first got internet from them, so i'm not required to use theirs or anything.

main reason being aside from old modem that cuts out sometimes.. over a year ago, i got banned from a forum cause i decided after a couple years of using that forum that i didnt like the funky name i had and stupidly i made a new one, against forum rules apparantly.
i changed IP, email...etc. but after a couple posts they find me out and ban me again. how i dunno, i assume subnet since its always the same.

i asked admin about it and apologized for new name but then they ban me from even viewing anything at the site. got tired of making new emails,names..etc. i even change my passwords, it only works temporarily then i'm IP banned, and somehow asking questions gets me a harder ban.

could stand a new modem anyway, i'll just tell ISP it crapped out but not sure if i'll get new subnet ip or not

The chances you'll get a new IP are good. Perhaps the new IP you get will be in a different subnet than you're in now. Have you ever cleared your cookies before going back to the forum and signing up under a different name?

thanks for responding. yes i've cleared everything, i mean i re-format often. as a technet subscriber, i reinstall OS's all the time for other stuff on my main computer.

since the initial ban, i've upgraded my entire PC a couple times, new Router, the only thing i have thats the same is the actual Modem. whenever i do, sometimes i'll create a new account, password,email,unplug modem overnight to renew IP yet admin eventually catches me, not sure how exactly.

its not so much that i really cared about the ban, plenty of forums out there for computer help. i just really liked one in particular due to the communities knowledge in computer technicals and baffling that their so strict on me abandoning one username and creating another. rules are rules but no warning and ignored my explanation and apology is a bit rude.

is it possible that this administrator of no mercy is looking at the location of my entire ISP, rather than IP's? i know mine shows to websites as comming from a specific town.
might also explain why i get re-banned after a few posts or is it definitly subnet?
either way, i have been meaning to get a new modem anyway, should be more stable at least but i want to make sure before i tried to create new account again.

They probably look at the entire block of IPs that your ISP is assigned for your area. Can't be 100% sure though until they tell you, but they're not going to reveal that secret.

for reference to others, got a completely different brand modem.took almost 30 minutes over the phone to get it activated, up and running however i got same subnet and even exact same IP. even after having router,modem unplugged all night before i switched.
on the bright side my net speed is alot more resposnive
