BIND 9 windows XP builds

[Darcy Kevin (FCA)]

I guess I'm not so worried about a non-Internet-connected Windows XP box forwarding to an Internet-connected box that's running a modern (preferably non-Windows) OS. Assuming that the BIND versions are patched up to date, of course.

To be sure, all things must come to end, and XP support for BIND is no exception. But, the risk calculation runs something like: is there still enough critical mass of BIND-on-XP out there that there is a *bigger* risk incurred by no longer incorporating new security updates, or, has the population dwindled to the point where *only* the withdrawal of support will get the remainder to upgrade/replace/refresh their XP boxes?

Yes, I suppose not every machine running BIND is connected to the Internet. But how many are network inaccessible to every machine that
*is* connected to the Internet and might be compromised?

We run a local BIND for our LAN to avoid HOSTS files, but that same machine is connected to the Internet -- and runs a different instance of BIND to be authoritative for our domain. (No, not a separate machine, it's a very small installation.)

So, how many BINDs are completely isolated from the Internet, even under transitive closure of the internal network? It's surely a proper subset of all instances of BIND, but I doubt if it's other than a quite small subset.
