I'm guessing that someone stuck records like: 10.14.22.11 A 10.14.22.11 in your system at Cornell? Otherwise, normally, the CNAME record above would cause errors (i.e., if "10.14.22.11" were not a name, as well). You can't check this with 'nslookup' - you need to use 'dig'. [Nobody need respond with the well-known merits and failings of 'nslookup'.] -- /*********************************************************************\ ** ** Joe Yao j...@tux.org - Joseph S. D.
