DNS scavenging question

Last Modified: 2014-02-22
When does DNS define when a record is stale? Is it when the computer is off the network or has not reported to the DNS server within a certain amount of time?

I have DNS records that have TTL set to like 20 min. Is this normal? We get DNS records that seem to vanish for no reason and we have to manually put them back in.

My recommendation is as follows:
Post http:#a39780100 answered the questions posed by the asker.  I recommend this be the accepted solution.
Though not specifically asked about, post http:#a39784082 provided a good explanation of TTL.  I'm fine with this as an assist.

Footech's right. I didn't answer the main question - he did, and I supplied some extra info, so he should get most of the credit.
