DNS Questions

Two parts:
1. If you change the serial number on a zone record to a number that is less than the original does that count when Internic updates its cache?

2. Can someone post an example of a perfect zone record? Bind 8

Thanks

1. No, it has to increment to trigger the update AFAIK.

2. Perfection with BIND is hard to find :) Anyway, here's an example:

;
; Zone file for bogus.domain
;
; The full zone file
;
$TTL 3D
@ IN SOA ns.bogus.domain. hostmaster.bogus.domain. (
   200106121 ; serial, todays date + todays serial #
   8H ; refresh, seconds
   2H ; retry, seconds
   4W ; expire, seconds
   1D ) ; minimum, seconds
;
  NS ns ; Inet Address of name server
  MX 10 mail.bogus.domain. ; Primary Mail Exchanger
  MX 20 mail.bogus.domain1. ; Secondary Mail Exchanger
;
localhost A 127.0.0.1
ns A 192.168.0.2
mail A 192.168.0.10
