R.I.P. IPv4

R.I.P-IPv4

It has been nearly six years since the last available IPv4 addresses from a central pool were allocated. In the intervening time, the five regional registries have allocated the remainder of their IPv4 addresses, meaning that this addressing protocol has now run its course.
There are several reasons as to why IPv4 has been completely exhausted, not least the pitifully constrained amount of addresses that were made available in the first place, but the advent of IPv6 has enabled Internet users to remain online and the evolution to the new protocol has generally been seamless.
The infographic below charts the conclusion of IPv4, outlines why this exhaustion occurred and explains how IPv4 addresses can be migrated to IPv6.
