Re: Dynamic IP won’t change

Comcast's dynamically assigned IP's are what as known as being *sticky dynamic*. Why do you need it changed ?

Re: Dynamic IP won’t change

I need it changed because I’m getting ddos and people are stressing my ip then when I get a new ip I will get a vpn. Is it possible for me or my isp to change my stick dynamic.

Re: Dynamic IP won’t change

If you have a router that has a MAC address cloning feature, you can clone a different MAC address in to it. This will force their DHCP server to assign a new / different public IP address to your connection.

 

The Comcast supplied gateway devices do not have this feature.

No. As stated, the MAC address of the device would need to be different. Their dynamic IP are tied to the MAC address of the router.
