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.
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.
You can try but don't hold your breath. Good luck !
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.
