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.
