I prefer to use:
zone "localhost" {
type master; file "db.localhost"; };
zone "1.0.0.127.in-addr.arpa" {
type master; file "db.localhost-rev"; };
zone "1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa" {
type master; file "db.localhost-rev"; };
with just the two master files:
(db.localhost)
; Like empty zone, but modified for zone "localhost"
@ 86400 SOA localhost. . 0 28800 7200 604800 86400
@ 0 NS localhost.
@ 86400 A 127.0.0.1
@ 86400 AAAA ::1
(db.localhost-rev)
; Like empty zone, but modified for reverse lookup of "localhost" (IPv4 or IPv6)
@ 86400 SOA localhost. . 0 28800 7200 604800 86400
@ 0 NS localhost.
@ 86400 PTR localhost.
