You could configure your DNS server to have a proper reverse zone for 
the IP address range involved.

Probably via the $GENERATE syntax listed in section 6.3.6 in 
http://www.bind9.net/arm910.pdf

(Yes, that's the ISC BIND 9.10 manual; current.   That's not what 
OpenVMS has, if you're using OpenVMS as your DNS server.   I checked 
the BIND binary for what appears to be support for $GENERATE, as the 
BIND 9.3.1 version provided with OpenVMS is ancient.  $GENERATE has 
been around for a while, so you're running your DNS server on some 
other implementation of ISC BIND, then it's almost certainly newer than 
what OpenVMS offers with TCP/IP Services.)

I'd suspect this is associated with accounting.  Off-hand, I don't know 
of a way to disable it.
