RIPE NCC on last IPv4 /8

RIPE NCC the European IP registry has today reached the last /8 of IPv4 address (a /8 block means x.255.255.255 so there are 16.8m usable addresses). Local registries will now only be able to apply for single /22 blocks (i.e. 1024 addresses).

Though the use of IPv4 addresses has been reduced by utilising methods such as dynamic IPs and network address translation (NAT), the explosion of connected devices means that IPv4 space is now close to being used up. Registries will only be able to get these last be blocks if they already have and are using IPv6 blocks.

The only rational way forward is for more Internet Service Providers (ISPs) to support the new IPv6 protocol and roll IPv6 services to consumers. Most current operating support IPv6 natively, though not all consumer routers/etc do.

The death bell for IPv4 is now ringing.
