Most BSD networks do not have dynamic DNS updating enabled on their
nameservers,
but that is the capability you seem to be asking about.  If your network does
have this enabled, it's possible that using dhclient to release and renew a
DHCP
lease on the BSD machine would be the right approach.

Otherwise, change the zone file on the primary DNS server directly by hand.

Heres the situation 

I'm in windows environment mainly, I recently setup a BSD box (static IP, and
DNS pointing to the windows DNS server)

With Exim, SA  and CLAM_AV

All has been running relatively well (3 months give or take)

Till today I started getting this:

milter# freshclam
ClamAV update process started at Mon Dec 12 15:05:34 2005
WARNING: DNS record is older than 3 hours.
WARNING: Invalid DNS reply. Falling back to HTTP mode.

Google gave me 

http://www.google.com/search?hl=en&q=DNS+record+is+older+than+3+hours&btnG=Go
ogle+Search

One tell me that's its ok
There is no reason to be concerned - most likely you have a caching DNS
server at the gateway and this is causing it. DNS query is designed to
minimise load on the datbase server when determining if the database version
is uptodate. But if this method fails it would just query the database server

The other , leaves me wondering
I get this error when running freshclam: Invalid DNS reply. Falling back to
HTTP mode or ERROR: Can't query current.cvd.clamav.net . What does it mean? 

There is a problem with your DNS server. Please check the entries in
/etc/resolv.conf and verify that you can resolve the TXT record manually:
$ host -t txt current.cvd.clamav.net
If you can't, it means your network is broken. You'll be still able to
download the updates, but you'll waste a lot of bandwidth checking for
updates.
