Can't speak for all Telco's but in Australia, DOCSIS modems are registered by their MAC address on the modem it's self. Not by IP address. I can't imagine this

I can't imagine this is different else where so it's likely the replying comment above yours is incorrect.

- dangerface 5y agoVirgin used to just use the mac address with their old modems, you could flash the firmware and change the mac so you could buy their cheapest package and flash the mac of a modem with unlimited gbit internet. They craked down on that a few years ago tho so I don't think this is possible anymore.
- lxgr 5y agoModern DOCSIS also uses certificate-based authentication. Only the owner of a given MAC OUI is able to create a certificate covering MACs under it that will be accepted by the CMTS.
- lxgr 5y agoRegistration/network access and management are two different things, no?
- LilBytes 5y agoNot always, with Telstra the MAC address was also responsible for authentication. Though I believe it's since changed, my last interaction with DOCSIS was 4-5 years ago. I seem to recall there's a captive portal involved now but previously it was solely MAC.
