IPv4 Address Allocation Screensaver
The IPv4 Address Allocation screensaver shows how much IPv4 address space is delegated to each country in the RIPE region, from RIPE NCC's key-less published statistics. IPv4 space is finite and essentially fully allocated, so totals now move only through transfers. It's free, runs in your browser, and ESC exits.
How the IPv4 Address Allocation screensaver works

Frequently asked questions
- Is this real data?

- IPv4 space is finite and essentially fully allocated, so country totals now change through transfers between holders rather than fresh allocation.
- Is a key needed?
- No. This source is fully key-less.
- Is it free?
- Yes — free, no download, in your browser.
