RIPE NCC IPv4 Address Space Chart

RIPE NCC IPv4 Address Space Chart

Today we allocated the last of our contiguous /22 IPv4 address blocks. We still have approximately one million addresses available, in the form of /23s and /24s, and we will continue making /22-equivalent allocations made up of these smaller blocks. Once we can no longer allocate the equivalent of a /22, we will announce that we have reached run-out. We expect this to occur in November 2019.

We currently have around 1.91 million IPv4 addresses remaining in our available pool. We expect to reach the end of this pool in the next few months, before the end of 2019. The exact date is not possible to predict as this depends on the rate at which new members/additional LIR accounts are opened.
