Static IP Address and Contract renewal

Vc5JwX8b — Fri, 28 Nov 2025 22:14:49 GMT

I currently have a static IP address, my contract period is coming to an end in January, if I renew the contract will I loose my static IP?

I'm also concerned that if static IP is not mentioned in the new contracts, then plusnet could decide to remove it at a later date ( within the 24 months of the new contract ), has anyone seen any statement on that?

In case there's no certainty on static IP for the length of my new contract, what's the best way to cease my line such the it's done aligned with the end of my contract? (i.e. so I don't have an early termination, or end up paying a month at out of contract prices )

Static IP addresses are associated with the account, not the service. There has been no mention of termination of static IP addresses.

Thanks, I'd read https://comparebroadbandpackages.co.uk/guides/news/broadband-isp-plusnet-uk-discontinues-static-ip-address-option/ which states

"Impact on Existing Customers

Current plusnet customers with static IP addresses will be transitioned ⁢to⁣ dynamic⁣ IP addressing according to the following timeline

"...

Of course that may not turn out to be true.

I do wonder why they'd want to drop static IP, it's not like many folks turn their routers off these days... so it doesn't "save" ip addresses, unless it's in preparation for CGNAT.

CGNAT is used by any ISP that has more customers than they have IPv4 addresses - that can include mobile companies, but also many ISPs. Even my ISP (altnet Gigaclear) apparently has deployed CGNAT in some areas, although I have a static IP so I'm not impacted by that.

A few years ago there was a big shortage of IPv4 addresses, as all of the available address ranges were allocated, leading to widespread use of CGNAT. However since then a lot of companies with large blocks of addresses have moved to IPv6 internally and released some of their IPv4 address blocks, so there are more available than there were. However, that can lead to geolocation issues where an address that was used in one country becomes allocated within another country.

@corringham But, as I understand it, if a range is moved geographically, that should have no effect, other than to say that - where services are location dependent - sorry, you are not in an area which can access this service, usually, but not exclusively, where an entity does not have rights, or you don't have rights to access the service.

Unfortunately, when geolocation services fail to update their databases correctly - I'm thinking of the considerable number of ranges that BT moved from the Americas to the UK - then you get major problems, when either they, or their subscribers are using out-of-date data.

@jab1 that is exactly the geolocation problems I was referring to.
