I'm replacing Caching and Forwarding DNS server (called CS) in Bind 9.16.23
which forwards all client queries to specific server Z.
My doubts:
1)
This CS server doesn't use root server so I can delete in named.conf this
section ?
zone "." IN {
type hint;
file "named.ca";
};
2)
the original named.rfc1912.zones file contains these zones:
-------------------------------------------------
zone "localhost.localdomain" IN {
type master;
file "named.localhost";
allow-update { none; };
};
zone "localhost" IN {
type master;
file "named.localhost";
allow-update { none; };
};
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"
IN {
type master;
file "named.loopback";
allow-update { none; };
};
zone "1.0.0.127.in-addr.arpa" IN {
type master;
file "named.loopback";
allow-update { none; };
};
zone "0.in-addr.arpa" IN {
type master;
file "named.empty";
allow-update { none; };
};
-------------------------------------------------
My old file contains the same entries, excluded 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,
and It includes the followind extra ones:
zone "127.in-addr.arpa" {
type master;
file "db.127";
};
zone "255.in-addr.arpa" {
type master;
file "db.255";
};
file db.255
$TTL 604800
@ IN SOA localhost. root.localhost. (
1 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
@ IN NS localhost.
file db.127
$TTL 604800
@ IN SOA localhost. root.localhost. (
1 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
@ IN NS localhost.
1.0.0 IN PTR localhost.
What do you think ?
I can delete both "127.in-addr.arpa" and "255.in-addr.arpa"zones ?
And about
"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
zone ? I have t keep it ?
Thanks
