Hi Igor,

long time no speak, my newgroup moderation box is still happily

We don't do "spam" traps as the newsgroup is also sent by
e-mail.

The SOA doesn't define TTL on modern copies of BIND. Usually the
default is in the $TTL line at the start of the file.

Looking from here algebra.com has 7200 set as TTL on most
records.

No - alas.
  
Also how would you find the caching name servers of all these
ISP's?

The AOL name servers listed by dig look not to be the caching
DNS servers.

Without the config files I wouldn't hazard a guess.

The delegation data lists ns5 and a classifiedmonster server.
The second of these isn't playing at the moment.

ns5 allows zone transfer.
oops "#" is not a comment character in a zone file, try ";"
Any reason for that PTR record? Just curious on that one.

	Keep up the good work,
