Adding a new domain – a simple example

Adding a new domain – a simple example

This article describes how I added a new domain,, to my DNS.

article is not comprehensive.  I know there are gaps which may confuse people who are
new to DNS.  Please try Getting local names to resolve

The zone files

When you register a new domain, the first step is to create the domain on the name
server.  I will assume you already have named running and configured
properly.  Hopefully, Getting local names to resolve (DNS)
will be helpful if you need to get named running.

The first step was to create
the zone file, /etc/namedb/   In this example, the
following points should be noted and the details modified to suit your situation:

  • the best source of information for this zone is
  • the contact address for this zone is
  • the name servers for this zone are and
  • there are two names defined for this zone: and,
    both of which are aliases for, which is defined elsewhere.  You
    may wish to use examples from my zone files.
@       IN      SOA  (
                                199910281       ; Serial
                                3600            ; Refresh
                                900             ; Retry
                                3600000         ; Expire
                                3600 )          ; Minimum

; name servers

                IN      NS
                IN      NS

                IN      MX      5
; Define the rest of my subnet

www                             IN      CNAME
mail                            IN      CNAME


Modify named.conf

In order for named to use this zone file, you modify named.conf to include something
like this:

zone "" {
        type master;
        file "";

And then you restart named like this:

ndc reload

Register the domain

Now you should register the domain.  I always use
Well, I used to… until this happened. Since then, I’ve always used an
OpenSRS reseller.

But what about email?

The above isn’t quite enough to allow you to send/receive for this domain.  For
that, you must allow sendmail to relay mail for the domain in
