What does it mean by “still overspending on IPv4”?

IPv4 blocks are expensive. If you’re not paying for them directly, then your service provider is paying for them and passing the cost on to you.

Alright, that’s totally understandable. As a service provider grows, it needs to obtain more and more IP blocks. Are there ongoing costs to owning a block of IPv4 addresses, or is it just a one-time purchase fee?

One-time AFAIK

There technically is an ongoing fee to keep your membership (at least with ARIN there is) but it's so small to be meaningless.

Some providers rent their ipv4 blocks rather than purchase them, because the smallest volume you can buy in is 1024 addresses which is pretty expensive, especially for newcomers. In that case there would be an ongoing cost.

You can get /24's (256 addresses), you don't need to get a /22. Anything with a longer prefix is not generally allocated by regional internet registries, and won't usually be accepted over BGP.

Oops, major facepalm, forgot /24 was the actual smallest size. It's too late to edit my comment to fix it sadly.

On the open market they are currently $45-$55 USD per IP depending on block size.

So a /16 (like a cloud provider would be buying) is $3.5M USD right now.

I think around 7-8 years back, a VPN with ipv4 was $1.5 per month more expensive than one with ipv6 only. It should have been much more now.
