It _IS_ a good idea to not use any kind of descriptive names in your PTR records (e.g. macerver.mydomain.com, hackable-NT-server.mydomain.com, etc.) But you can always set up reverse that simply say 111-111-111-111.mydomain.com (the ip). But you MUST have forward entries for those reverse entries... -- Joe Laffey | Want to convert subnet masks between different LAFFEY Computer Imaging | notations, or figure the number of IPs in a block?
