Re: Address recycling
I'm sorry, but no.
Certainly, it is easier (today) to grab of 2^48 or so addresses and not worry about proper address management. But sloppiness is what has gotten us into this mess.
Subdomain mismanagement is a major problem with Microsoft. Now we see that they are "industry leaders" instead of outliers.
If you properly manage things like DNS records, it's going to take a significant amount of effort.
If you don't properly manage things like DNS records, you are going to have a bad time.
IPv6 might (might) allow you to get by with pretending that you can orphan IP addresses for a while. But the pain you will be in when it all falls apart (and it will), will be orders of magnitude more severe than when you are stuck with 32 bits for the entire world to play with.
