[Hidden-tech] Strange DNS Behavior

[Gyepi SAM]

The address is cached by whatever server you are using. If you control the
server (doubtful), you can clear its cache. Eventually, the record will expire
and things will work fine. If you need this to work immediately, change your
DNS server address on your work station, router, etc to another server that
hasn't already cached the old record. If you just want to see whether the
change worked, you can use the hostname utility and query different DNS
servers.

BTW, the correct way to solve the problem is to avoid it in the first place
by reducing the TTL values for your DNS records to a low value before you make
the switch so that the old records expire quickly. Most DNS servers default to
86400 seconds (24 hours), so you need to make the change more than 24 hours in
advance. The "right" way is to ratchet the values down over time for better
control and to avoid traffic bursts, but for most sites, the simpler method
works just fine.

Hope that helps! I know there's a lot of technical 'mumbo jumbo' in my
response but since you're holding a wrench, so to speak, I doubt the
simplified version will be of much use to you.
