Now, what exactly is the relationship between this entry (The dsl line @ pacbell) to that of my dial-up connection through US Worst?
If 209.233.142.18 is the IP address that showed up in your logs, then that's the address the packets were launched from. Maybe you've got some extraneous nameserver information from UW - though as they're not authoritative for the domains in question, or maybe you're misinterpreting the data. FWIW, ns1.pbi.net and ns2.pbi.net show the same address, that's a no-no. Paul ----------------------------------------------------------------------------- Paul D.
