Changing MX IP Address?

[Joe Kattner]

Dan,

You can reduce the TTL for the host(s) moving, lowering it as the move date
approaches. That way, the cached data that is propagated will expire more
quickly, and force more queries to the authoritative name servers. Once
moved, then you raise the TTL back to what you normally use.

Do you have a secondary mail server to use, and perhaps set up before moving
the primary?

Hi,

We will need to change our MX IP Address due to a change in ISP.  My
question is how can we assure that this IP Address change gets
propagated throughout the DNS system so that disruption to email is
limited.  Any advice is appreciated.
