Thank you for that article, insightful. I would not, however, suggest 
that IPv4 is simple. It stopped being simple 30 years ago. The only 
people who see IPv4 as simple are too close to the protocol that they 
don't see the issues that IPv4 inevitably has, such as the NEED for NAT, 
address conflicts, and the complexity that comes from the fact that 
related systems are unlikely to have addresses in the same network 
nowadays.

I'd rather memorize the 16 bits of network that are actually under my 
control in an IPv6 network (the first 48 bits are always the same inside 
my prefix, and I don't have to care about the last 64) than 32 bits of 
IPv4 addresses for a reasonably complex system.

Greetings
Marc
