If none of the IPs work, you will most likely need to call us to verify they are still correct for your location. If one works, but others don’t or they all work randomly you will need to get in touch with us. Only one static IP is allowed to work on a CPE (customer premise equipment).
If you plan to use more than one IP on the same CPE, that requires special permission on some of Suddenlink’s equipment to work right. Cable Host Authorization is required on most of our CMTS (cable modem termination system) to allow more than one static IP on a CPE on the network.
