   I see this question alot.  And I've seen some very brief answers that
have left me sometimes more confused just when I though I was finally
catching on :-(   I've looked through the "DNS and BIND 3rd Ed." for
information and *examples* on the use of the $TTL directive and found
nothing.  Okay, I'm stupid... 

   Checked the index in the back.  Under T for TTL it lists some pages.
Read 'em. Still not clear.  Looked under the 'symbols' at the beginning of
the index.  '$' is not even listed...  Okay, where in the 480 pages do I
find information about this puppy?

   Could someone who's in the know humor me (and the others that want to
know). <I>Please</I> cut and paste in an example of what the $TTL is
supposed to look like.  Please include the entire SOA record so we can see
how it all goes together... 

   Thank You,
