What do the following mean, and what do they do?

TTL
Refresh
Retry
Expire

I *think* TTL is Time for DNS entry to live before it forgets the
entry.  But if that's the case, then why is Expire there if TTL does the
same thing?  Refresh I *think* is when it re-loads the DNS entry from the
main server, and retry I *think* is how often it tries to get a DNS entry
until successful.

Please correct me on my thinking so that I understand this.

Thanks.

Sincerely,

Rick Duvall
