I have static ip address and would like a dynamic!

I have been getting too many DoS  attacks which is slowing my internet service! I want a dynamic internet service! I want my ip address to be constantly changing! Why they say dynamic and give you static? I looked online the only people getting static ip address are businesses not regular consumers?

After you change your router's MAC address, you MUST reboot your modem. That forces Comcast's servers to then notice the MAC change and update accordingly.

FWIW. And It's the cable modem's MAC address cache that needs to be flushed of the prior MAC address for it to be able to recognize and accept the new MAC address in order for it to be able to re-obtain an internet connection. And it does so when the modem is power-cycled.

Thank you guys so much! Hopefully now all the DDOS attacks will stop! Someone was crashing my PC. The help is much appreciated and I am glad there are people like you who do not hesitate to help even on a Saturday!

Standard home Comcast HSI is dynamic. but it is 'sticky'. It is based on the MAC address of your router (or built-in router of a gateway.) It can often hold for years. If you want to change it, you can alter the MAC address of your router and then reboot the modem. If you have a Comcast gateway, you may be able to find a smart enough service agent to force a reprovision. Otherwise, you may have to swap it for another one.

I have my own equipment. I am using a Netgear Nighthawk and I have tried changing the MAC address and I was unable to get the internet to work; forcing me to revert all my changes! I even called xfinity tech support and the person said I have a static IP address and I asked him to change it to dynamic and he said he well have someone call me! I have regular internet service I am not a Buisness subscriber. I will try altering the MAC address and see if it works but if you have any links that could help it would be much appreciated.

I am still getting attacked after changing my IP address and using a VPN. Every time I run a speed test I am not getting the usual speed. Here is my router log.
