Yep. No problem. DNS is not designed to be a strict one-to-one mapping, and there are a lot of situations where pointing many names at the same IP address is very useful. Technically you can also have multiple PTR records for making reverse DNS work for all those names as well, but not many tools that use PTR records will grok that. -- Bill Cole [EMAIL PROTECTED] ############################################################# This message is sent to you because you are subscribed to the mailing list <[EMAIL PROTECTED]>.
