sorry? v localhost zone by mal byt len localhost (to iste pre reverzku).
potom mozes mat este zony pre tvoju siet.

v localhost zone by nemala byt ziadna masina navise, a localhost by nemal
byt v ziadnej zone navyse.

ma zmysel to tam pridavat, aj to vyzaduje RFC1912:

<CITE>
4.1 Boot file setup

   Certain zones should always be present in nameserver configurations:

           primary         localhost               localhost
           primary         0.0.127.in-addr.arpa    127.0
           primary         255.in-addr.arpa        255
           primary         0.in-addr.arpa          0
</CITE>

nema vsak zmysel tie zony spristupnovat zvonku, nakolko by sa s nimi kazdy
nameserver mal vysporiadat...
