I've spoken to the comcast employees about changing my IP multiple times they send me the same link everytime
it does not help me I've gone through multiple attempts of changing my WAN IP which remains the same everytime time I've tried I call back they send the same link or just tell me the steps acting like they cannot change my IP address it is extremely annoying and irresponsible, I am constantly being ddosed and receiving ddos threats but the employees at Xfinity do not help in any way. I just want help.
That link might change your LAN IP, but it won't change your WAN IP. To change your IP see https://forums.xfinity.com/t5/Your-Home-Network/I-have-a-dynamic-Ip-and-my-ip-wont-change/m-p/338410....
I've seen hundreds of similar requests here in the Forums over the more than a decade, and AFAIK Comcast has never granted a single one.
This is a little drastic maybe, if you rent a gateway from Comcast, just upgrade it, depends on what you already have, you will get a new ip
