Which does suggest they have merged the ownership of IP Addresses then, as you implied. I wonder what EE customers are seeing.

Same for me. Fixed IP but shown as owned by BT. My location is shown as Burmarsh which couldn't be much more wrong. I'm currently connected to a Colindale gateway if that is what is being detected, but I thought that is somewhere in London.

Geo IP in the UK is useless in the main

Have you actually done a whois on your IP address, rather than what others are trying to figure out based on the AS number.

In short a lot hinges on what fields are used to ID connections, AS6871 has an as-name of PlusNet but an org-name of British Telecommunications PLC

A whois does actually show it belongs to Plusnet.

Same here, used to say Plusnet.

If you use https://www.iplocation.net you can see several Geo IP companies and their guesswork.

In my case with my static IP Plusnet FTTC / VDSL connection I get these responses:

IP2Location = British Telecommunications PLC
ipinfo.io = British Telecommunications PLC
EurekaAPI = PlusNet Technologies Ltd
DB-IP = Plusnet Technologies Ltd
MaxMind = Not Available

Proving MrSaffron's statement - its all guesswork.

A WHOIS from RIPE on my static IP reports:
descr: Dial-up and ADSL pool
descr: PlusNet Technologies Ltd

IP blocks move between organisations all the time, and when its a big corporate like BT PLC then it can take ages to update WHOIS.

This has got me thinking.. I'm sure that a year or two ago I was able to have a change made that resulted in a reverse lookup of my IP address returning just the IP address whereas it now returns my domain name. Is my memory playing tricks on me?

Your memory isn't playing tricks as I remember a few complaints around that time for the same reason.

Although, do you remember some years ago Andrew when I posted about a company called Maxmind (think that was the name) that had a pretty accurate GeoIP lookup for the UK.
Last time i looked I couldn't see the free GeoIP look up feature on their website. In comparison to the competition even back then for UK GeoIP lookup they seemed to be streets ahead on accuracy.
