[thelist] DNS caching? Tips to override, refresh DNS?

[Joe Crawford]

A little hard to explain - but we have a client site which changed hosts
and DNS recently, but the DNS has not propogated to everywhere on the
net.

How does one go about getting local DNS administrators to get a fresh
copy?

Examples of people with the old version:
        - people on cable modems
        - people behind firewalls
        - people behind proxys

Any tricks for these people to query their local DNS controlling server
so that it gets a fresh copy?

I only half understand how DNS works - so simple explanations would be
best.

        Thanks!

                Joe
