That's what DNS is for - so you can change IP addresses while using the same name. CNAME's are useful for that function as well. >I don't imagine that I'd > see any performance improvement with this, but will I lose out. No performance problem (at least nothing significant) if you want to do it this way. It won't hurt anything. > > Is there strength to my logic, or am I being silly here? > It's a good idea to keep things seperate at least by DNS name (even if they point to the same IP). It makes it much easier to move things around as needed. Your doing pretty much what we did when we started. The biggest mistakes we made were hardcoding DNS for some customers and using machine names (rack0.amplex.net) instead of role names (pop3.amplex.net) for some things. > TIA > > Tom Wiebe Mark Radabaugh Amplex (419) 833-3635 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
