;;         Minimal DNS Zone Sample.
;;         ------------------------
;;
;; NBs : 
;;  - Assume BIND > 8.2 (else modify $TTL and TTLs units)
;;  - Here TTL's value are very small for testing
;;  - XXX means to be replaced by correct values
;;  - !ALERT! Current zone name is implicitely concatenated 
;;      to domain name without final dot. (FQDN completion)
;;  - !ALERT! Serial number needs to be modified every time the file
;;      is modified

;;## Default TTL value for RR

$TTL  5m        
            
;;## Zone Identification (Mandatory and uniq in the zone)

@   IN     SOA  (  
         NS1                      ; this (primary) server
         XXX\.XXX.int-evry.fr.    ; administrator's mail 
         2005XXXXXX   ; Serial Number : YYYY/MM/DD/xx (4+2+2+2)
         10m          ; refresh TTL for slave update
         1m           ; retry TTL, if problems in refresh 
         1h           ; expire TLL, if big problems in refresh
         1m           ; Negative Cache TTL (TTL for NXDOMAIN response...)
                )

;;## Authoritative Servers for this zone (Mandatory)

@          NS    NS1              ; here, a uniq server (not good!)

;;## NS1 Address (Mandatory from previous)

NS1        A     157.159.XXX.XXX  ; IPV4 Address for NS1
   ;;!! ALERT: Don't modify NS1 line without modifying !!
