Last of the Ipv4 address space.

Those of you following the recent tech news will no doubt have come across the tidbit about the last of the unallocated ipv4 blocks.

We are down to 5 prefixes, one of each which will go to the 5 Rirs.

Have we run out of space? No… But the unallocated pool is looking shallow these days. 

The move to ipv6 will be gradual as there is still a lot of debate about the features and pitfalls. It is a major paradigm shift in the way we consider networks, routing, address allocation and the like.

More to come as I get back in to my blog.
