BIND9 - Can I map a simple hostname to a domain name?

I have a BIND9 DNS server running on a company network that has a single master zone company.example and everything else is forwarded to the company DNS. I have managed to map server1.company.example and server2.company.example to their respective IP addresses, but I would also like to reach them by simply using their hostnames server1 and server2.

Any ideas on how to achieve this?

I tried using CNAME like shown below without any luck

$ORIGIN company.example.

...

server1            IN    A   4.5.6.7
server2            IN    A   4.5.6.8
server1.           IN    CNAME server1
server2.           IN    CNAME server2
Solution

  • You need a new SOA record as server1 and server2 are not within the company.example. domain. You would also have to append a . to your SOA record:

    ; Start of Authority
server1.   IN   SOA   ns1.example.com.   support.example.com. (
          XXXXXXXXXX  ; Serial
              XXXXXX  ; Refresh
               XXXXX  ; Retry
             XXXXXXX  ; Expire
              XXXXXX  ; Minimum
);

    Disclaimer: I haven't actually tried this record as my nameservers are live :)
