What do you get when you do "host database.clamav.net" ?


Yea, doh. Is the DNS supposed to return a RR based on your location?


Actually, for database.clamav.net, the answer is yes.
Or to be specific, based on your IP address.
It's an effort to balance mirror load among mirrors.



Ok, so we've established that it's supposed to figure out your region
based on your IP, and we've established that for several of us it is
failing. Why? Anyone know how that was set up?


The primary reason database.clamav.net was split into several regional zones was
to avoid gigantic DNS reply, which would require TCP instead of UDP.
Instead of returning all mirror IP addressess, it returns only several
addressess "closest" to you (based on your IP region).


Some firewall admins block the DNS TCP port, which (back in the old days)
makes the command "host database.clamav.net" failed.

The current configuration SHOULD solve this problem.
e.g. If you get IP lists for database.clamav.net that means
you don't have the DNS TCP problem.

I don't think I know
enough about DNS to troubleshoot this....  (I'm pushing the issue
because it seems like the "other" mirrors are going to be overloaded if
this is a common problem.)



the "other" mirrors are selected from mirrors with plenty of bandwidth,
so overloading should not be an issue.
