192.in-addr.arpa is a "special" zone because it corresponds to a
reverse zone in which a popular portion of RFC1918 IP address space
For other IP address ranges, the number of RDNS requests about those
ranges is much more complicated than merely the 'amount of resources'.
It depends on how those IP resources are actually utilized.
If the resources are utilized primarily from mail servers, then there
are likely to be a great many reverse DNS requests for the ranges.
If no outgoing TCP connections are being made from those addresses,
then, the volume of RDNS queries made from them would be quite
If you want to be "fair" about number of RDNS queries or WHOIS
queries against a resource, then
and add a "variable portion" to members' annual maintenance based on
the volume of queries that were made to ARIN regarding their
(Cost to ARIN of providing RDNS services) DIVIDED by (Total Number
of queries against RDNS servers) = cost per query.
Resource holder's variable portion = (cost per query) X (number
of queries against that resource holder's IP addresses)
