Zen selling 65,536 IPv4 addresses - £44 per address

Perhaps Zen's growth has stalled and customers are migrating away to cheaper options during a period of bill rises elsewhere, or perhaps CGNAT is on its way to Zen customers who have previously been used to the luxury of an unchanging static IP.

Either way, posting a "we're flogging a /16" video on YouTube isn't a great look to those of us who are current Zen customers. Richard "way too old to be rocking that hairstyle" Tang could have spent just a few additional seconds explaining why the addresses are up for sale and reassuring current customers.
 
Strange thing to do as they offer static IPv4 for all customers, I wonder if they are also changing to GCNAT going forward for new customers, I know it’s excess of £2.8m for the /16.

Might have a snoop on ASN to see what they have at moment.

(you beat me to the reply).

They don't own a lot of /16s though - only four:
  • 51.148.0.0/16
  • 51.155.0.0/16
  • 51.170.0.0/16
  • 217.155.0.0/16
My home broadband IP is in one of the above (one of the 51s, which some Googling suggests was flogged off by the DWP in 2015). Looking at DNS records, all the other /16s also have a lot of customers in them, or at least people who've got domains pointed at various IPs in these blocks.

They only seem to own four /16s, so one of the above must be what's for sale, so there are likely to be customers who end up renumbered.

They have a /14. Could use one of the 4 /16s in there and advertise the 3 /16s separately. May also be DNS records are out of date and they haven't been allocating those addresses for ages to empty them.

I'd hope it's a dynamic range they've stopped allocating.

I hadn't spotted the /14 - not enough coffee today!

An old employer has a server in the /14 (82.69.x.x) and it still seems to be alive and pingable, so there are at least some active customers in there. I can't find anything inside 82.70 or 82.71, though, so it looks like one of those may be for the chop.
 
Yeah sounds like some customers will be shifted, don’t think RIPE allow transfers of split ranges once assigned bigger block, I believe it has to be the entire block (I could be wrong here)

I didnt bother going in to the less than a /16 but in total just them is around 3/4m IP's and going off the customer numbers on here of 175k I would say there quite a few more not being used as well.
 
£44 per address seems…quite high.

What’s the going ‘guide price’ for wholesale v4 address blocks these days?

Sound like Zen want to free up some otherwise dead capital.

What a waste, they used 70% of 16 million ip's internally.

70% of the massive block was used for the UK government's internal network, leaving about five million free for disposal.

I have an 82.71 address

No huge problem if I get moved as long as I keep a static address.

Sounds about right, Truespeed purchased our spare 1,024 addresses last year.

Same for me, I'm 51.155, but if I got moved it wouldn't be a huge issue as I'm just a home user and don't have a lot of stuff that's reliant on that single public IPv4.

Their IPv6 is great, and the vast majority of what I do online these days goes over v6, the static IPv4 is just a "nice to have". The bigger problem is that I've been with Zen for over two years and have only just memorised my IPv4 - I'm getting too old!
