No not a static IP.
PN do supply static IPs but most do not buy that add on despite it being a very reasonable one off £5 charge.
The PN dynamic IPs are managed by the BT Wholesale Multi-service Edge Broadband Remote access Servers (MSE BRAS). https://kitz.co.uk/adsl/MSE_BRAS.htm
There are many of these around the country.
I.E. smaller ranges of IP addresses depending on the exchange area.
When disconnecting and reconnecting the same IP is often re provided - hence the term "sticky"

I presume you mean Static I.P, never heard it called sticky before, but yes if they have one of them then it will stay the same

No I meant sticky not static, its when you keep your IP address (sometimes based on your DHCP Unique Identifier) even after a reboot but lose it if you say turn your router off for a prolonged period of time. Lots of provider do it nowadays.

Ah, I see what you mean. I don't take much notice of the IP address I use as I use a VPN anyway, and I don't really look at the router to see what it is. Even so I surprised that they keep the same address changing from FTTC to FTTP unless they have static IP address.

Learn something new every day

I know for sure I did not keep my IP address, not that it matters as I use a VPN anyway.

One reason for that is you changed ISP as well as "last mile" delivery technology.

LOL, I changed to completely different network, dropped Openreach

and you chose a network with a single ISP, rather than an open wholesale network (CityFibre or nexfibre or your hated Openreach).

Some areas have the ability to stay with the same ISP but also change "last mile" network. e.g. someone on Vodafone FTTC/Openreach may move to Vodafone FTTP/CityFibre and stay with Vodafone as the ISP and potentially stay with the same static IP. Not common, but not impossible.

I personally would prefer an open network provider, but unfortunately only one is building in my town, and they are again a single ISP network.

I agree entirely with you, I'm happy with Openreach as my underlying infrastructure provider and even if someone like Zzoomm then rocked up and became available I wouldn't switch to them. Cost and contract length are not everything.
