Is this zone file correct? Just to point a subdomain to another machine

Question

I am running bind9 on my home machine and hosting several zone files. This is working nicely and I am running various web services.

I now want to host a web service on an external machine (a Linode), and would like to verify that my host file looks correct;

In this example 1.2.3.4 is my home machine, and 100.101.102.103 is my Linode.

TTL 86400

example.com.     IN  SOA   ns.example.com. admin.example.com. (
                        7               ; serial number
                        28800           ; Refresh
                        7200            ; Retry
                        864000          ; Expire
                        86400 )         ; Min TTL

@           IN  NS      ns.example.com.

@           IN  A       1.2.3.4
ns1         IN  A       1.2.3.4
test        IN  A       100.101.102.103
www         IN  A       100.101.102.103

I want www.example.com and test.example.com to be hosted on my Linode, which will not be running bind, only a web server.

Thank you!

Darren

Answer 1

Where is your A record for ns.example.com?

The debate about using CNAMEs or multiple A records is up to you: DNS - Multiple A records or 1 A record and lots of CNAMEs?

Answer 2

This is correct. Requests for www.example.com and test.example.com will be directed to 100.101.102.103.
