Would it be the server (primary/secondary/master/slave) authoritative for the reverse zone containing the client IP address? The domain name of the client found via reverse DNS? The caching proxy server in between (at the client end, or perhaps at the server end)? What if it's a UUNet resold modem to a client of iAmerica - what server gets used then? We know that UUNet's DNS servers are likely to not be located close (in net terms) to the client, and how do we know what DNS servers are being assigned to the client? Or what if my clients get assigned dns servers in 192.168.254/24? Sounds to me like it's not a valid geographic identifier. Pete -- Peter J.
