If there are multiple 'CNAME's pointing to an 'A', then you only have *one* address to renumber and percolate through the planetary DNSs. I host various functions for several domains and 'CNAME's have been my friend. I try not to use 'MX's point to 'CNAME's, however, as that *has* caused problems. I am *amazed* at the number of MTAs that try 'A's even though 'MX's exist. 'CNAME's are not inherently evil in themselves, but some are misused - Jy@ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
