The information above was probably obtained using the excellent DNS Expert that comes with QDNS. There are a variety of other tools for MacOS, including AGNetTools and WhatRoute, that can also be used to do DNS queries. The advantage of DNS Expert is that it can analyze the DNS information it gets from queries, rather than simply displaying it and leaving analysis up to the user. You can also get the same info using either nslookup or dig on a *nix machine. With nslookup, you'd want to use its 'interactive' mode so that you can use the 'server' command to specify the name server you want to query. With dig, you can use the @ operator in the command line. Both nslookup and dig are described in a fair amount of detail in their respective man pages. Christopher Bort
