In general, the right-hand (data) portion >of _any_ record (MX, CNAME, NS, etc.) should be a canonical domain name. The exception is the CNAME record - you can chain CNAME records, though nobody recommends this practice. To reiterate, you can't use a name that has a CNAME record anywhere else, except in another CNAME record. This includes putting it in the data portion of another record, or in the name portion. A CNAME alias, for example, can't have an MX record or an NS record. To answer George's original question more fully, you can't use an IP address in any record except an A record. ____________________________________________________________________ Chris Buxton Men & Mice cbuxton@menandmice.com http://www.menandmice.com
