Zonefile example

On this page we give an example of a basic zone file and it's contents.

We recommend using the nsd-checkzone tool to verify that you have a working zone.

Creating a zone

A minimal zone needs exactly one SOA (Source Of Authority) and one or more NS (Name Server) records. Refer to appropriate documentation of you need to learn about DNS basics.

$ORIGIN example.com.
$TTL 86400 ; default time-to-live for this zone

example.com.   IN  SOA     ns.example.com. noc.dns.example.org. (
        2020080302  ;Serial
        7200        ;Refresh
        3600        ;Retry
        1209600     ;Expire
        3600        ;Negative response caching TTL
)

; The nameservers that are authoritative for this zone.
                NS  example.com.

; A and AAAA records are for IPv4 and IPv6 addresses respectively
example.com.    A   192.0.2.1
                AAAA 2001:db8::3

; A CNAME redirects from www.example.com to example.com
www             CNAME   example.com.

mail            MX  10  example.com.
