Normally when you buy a static IPv4 address you get a single "1.2.3.4". OP is basically saying they have access to something like "1.2.[0-3].[0-255]". /22 is a fancy way of describing that kind of slice in CIDR notation. So they have 256*4=1024 IP addresses in total.
- iFreilicht 3y agoI think it's 1022, as the first and last one in the block are the gateway and broadcast address, right?
- paxys 3y agoThat's the recommendation, yes, but even then all 1024 are in your control and you can do whatever you want with them.
- diggan 3y ago> Normally when you buy a static IPv4 address you get a single "1.2.3.4" Is it common to purchase (to own, not "rent" as what you get from cloud platforms) single IP addresses? I thought they were always bought/sold in blocks.
- paxys 3y agoI should have said lease instead of buy, yes.
- kdklol 3y agoNo, in general, the smallest block of IPv6 addresses you can "own" is /24. You have to pay yearly fees to your RIR (Regional Internet Registry) as an ANS (Autonomous system). Think of it as owning land and paying a land tax.
- icedchai 3y agoI have a /24 registered in the early 90's. I pay no registration fees for it since it's a legacy block.
