We really should get away from using IP addresses for identifying anything. At the DNS level you can use a EDNS option to identify the client rather than the IP address. I believe their Umbrella product does this. You can also use TSIG to identify clients independent of IP address. We added TSIG support to libresolv right at the beginning of the century. Mark
Incidentally, I hope OpenDNS considers 100.64.0.0/10 as space that can't be registered to any end-user. Aled
