Berkeley Internet Name Domain (BIND)

Bind 9

For decades it was BIND4 and it is a good reminder to be careful of versions in software. BIND can be thought of as one of the first DNS solutions other than hosts files.

Example config file

zone "example.com"
{
 type master;
 notify no;
 file "/etc/bind/custom/example.com.zone";
};

zone "113.0.203.IN-ADDR.ARPA"
{
 type master;
 notify no;
 file "/etc/bind/custom/113.0.203.in-addr.arpa";
};

zone "0.0.0.0.1.0.0.0.8.b.d.0.1.0.0.2.ip6.arpa"
{
 type master;
 notify no;
 file "/etc/bind/custom/0.0.0.0.1.0.0.0.8.b.d.0.1.0.0.2.ip6.arpa";
};

Example zone file "example.com.zone"

$TTL    3600
@       IN      SOA     example.com. email.example.com ( 1 1w 1d 2419200 1w )
@       IN      NS      ns.
@       IN      A       203.0.113.1

; 203.0.113.0/24 rfc5737
; 2001:DB8::/32 rfc3849

Example arpa zone for IPv4 "113.0.203.in-addr.arpa"

$TTL    1h
113.0.203.IN-ADDR.ARPA.         IN      SOA     ns.example.com. email.example.com. ( 1 1w 1d 1w 1h )
        IN      NS      ns.example.com.
1       IN      PTR     www.example.com. 
2       IN      PTR     ns.example.com.
3       IN      PTR     mail.example.com.

Example arpa zone for IPv6 "0.0.0.0.1.0.0.0.8.b.d.0.1.0.0.2.ip6.arpa"

$TTL 1h
0.0.0.0.1.0.0.0.8.b.d.0.1.0.0.2.IP6.ARPA.       IN      SOA     ns.example.com. email.example.com. ( 1 1h 15m 1w 1h )
                                        IN      NS      ns.example.com.
1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.1.0.0.0.8.b.d.0.1.0.0.2.ip6.arpa.       IN    PTR    www.example.com.
2.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.1.0.0.0.8.b.d.0.1.0.0.2.ip6.arpa.       IN    PTR    ns.example.com.
