That's a good idea. this will only affect those who have an updated record of your zone and can see that new record. For those that still think that MX is otto on it's real(old) IP, the CNAME wont help them a bit. Assigning otto's public IP to galley will fix this problem. Also, you may want to make triple sure the serial of your zone gets updated with every change...else downstream DNS servers wont necessarily pickup the changes. > I changed it and reduced the > expire time to 10d (I got it out of the Lehey Complete FreeBSD book).

I just beef up the DNS server and set it to 20 minutes - which equates to almost full propagation in about an hour or so (with most of the traffic updated within 30 minutes). **YMMV**. Best, beto
