Assuming the thinkbroadband speed test follows the RIPE ownership.
Basically that was what I was getting at. That Plusnet may not have updated RIPE or may be using an older copy of it. Or tbb using a none-updated site. But that it isn't an "incorrect" (as per the Subject) attribution.
You have moved on though to more up to date info that is far more useful than my previous post.
It does seem likely PN have just thrown the whole lot into their allocation pool.
My broadband basic info/help site -
www.robertos.me.uk. Domains, site and mail hosting -
Tsohost.
Connection - Three 4G, tbb tests normally 35-45Mpbs down, 65Mbps off-peak, 9-24 up.
