Should be -- this is standard practice for rDNS delegation when the rDNS responsible entity is not using an even octet-bounded network (/8, /16, or /24). In this case, it indicates a subnet of /27 or /26 (as the network boundary *seems* to be .192, though that's just thanks to the naming convention used by the upstream, and the customer in question has .200 as well). -- -- Todd Vierling <tv () duh org> <tv () pobox com> <todd () vierling name>
