A spokesperson for Zen told The Register: "We are making a change to the static IPv4 addresses allocated to less than 2 percent of our broadband customers. These are specifically customers with IP addresses within the ranges 82.70.0.0/16 & 88.96.0.0/16. All impacted customers will be notified on or before 29th February 2024."

So those affected should have been told a long time ago

But also considerably after the date of the comment you replies to

As it happens I was on the 82.70/16 network. I replied to Zen about how I use my IPs and they were very nice to not charge me to keep the same size net block (on the new network of course).

In terms of how many IPs were dished out back when Zen got their allocations. I remember when I was managing the ISDN on demand connection we had with Demon at work at the time.

A standard not that expensive business account with ISDN. They asked how many IPs we'd need. Now, this was before NAT was commonly in place. So I did a quick tally of machines and doubled it for expansioon. Total was 100 or so. They just said, oh you don't need to justidy a /24. And just handed us one.

So, yeah, it wasn't hard at all to get IP addresses back then.

But I bet they where allocated 'PA' - what you really wanted back in the day was 'PI' space you could take where you liked!
