Removing deprecated IP block

Many years ago, we were assigned the IP address block 64.238.220.0/23 by one of our upstream network providers. We officially deprecated the use of that block way back in 2008, and we will be returning it on December 1st, 2010, so it will not work after that point.

The only possible way this could affect you is:

1) You use third-party DNS to point at a site hosted here.
2) You hardcoded A records in the 64.38.220.0/23 range (against our advice) over two years ago.
3) You haven’t checked on / updated those settings in the past two years.

In other words, literally only a handful of people will be affected by this change. Nonetheless, we wanted to have at least some public warning before moving forward. The few people affected know a lot about DNS and went to the trouble to make a custom setup at another provider; they’ll know exactly what this post means and what to do about it. So, if you have to ask “does this affect me?” the answer is almost certainly no.

1. Yet another example of NFS’ social responsibility. It’s such a rare thing to see these days.

   One of many, many things that makes NFS so awesome.
