Change WAN IP Address on Customer Owned Equipment

[JMLiput]

Hello XFINITY Community,

Recently I have run into an issue that has required me to change my WAN IP Address, however with a customer-owned modem, Comcast has insisted it is not possible for them to renew the DHCP Lease to provide me a new IP Address.

Account Type: Residential

IP Type: Dynamic (No Static IPs on my acct)

I have escalated through Tier 1, Tier 2, and the Advanced Technician Queue. Always ending in the same result.

Has anyone else ran into this issue?

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