At least in the UK, if you use a BT line as GP mentioned (via OpenReach), they provide the physical connection but anything on top of that is up to the ISP. In OSI terms, OpenReach does layers 1 and 2, and the ISP is responsible for 3. That means your IP addresses, your IPv6 PD, etc are all on the ISP. If you change ISPs, it’s a whole new IP infra even if it uses the same OpenReach cables. |
