How to Bytemark

Content DNS (DNS hosting) service

‘Content DNS’ is the first service you need to provide when you want to host your own domain name on the internet.

Bytemark provide the vital ‘name servers’ which you can use to provide this service. They are called:

To ensure continuity for all domains that we host, we have a name server hosted in each of our Manchester and York data centres, and a third one on an off-site network in Amsterdam, which provides resiliency in the event of any network disruption, and any records served by one server will also be visible on the others. Read on to see how to put your data on them.

Using Bytemark’s content DNS Service

Symbiosis users

If your server is running Symbiosis this is taken care of behind the scenes. The Symbiosis documentation has the relevant information.


If you’re not using Symbiosis, you’ll need to get a copy of our upload script to manage your DNS data yourself.

After logging in to any Bytemark server run:

cd /root
wget -O

If you already have an account which you’re using, you may download an archive of existing data and an upload script. The correct Username and Password are to be found near the top of the upload script; please contact support if you don’t have a record of those details.

The archive will extract to a directory called BytemarkDNS (winzip or zip on Linux), which contains a script called upload and a directory called data. Inside the data directory, you will find a data file which contains some example data — you should copy and adjust some lines from this file to reflect the DNS data you want to host. Although not essential, it is a good plan to create a separate file inside the data directory for each of your domains.

You can edit the information and when it’s ready, run the upload script to push your changes to our DNS servers. This must be done on your server, as machines outside our network do not have access to the DNS servers.

cd BytemarkDNS

Then, with a little luck you should get the response Uploading to host : completed.

Once you are satisfied you have them set-up correctly on your server and the correct data has been uploaded, you can delegate your domains to our name servers:

You should find that your new/updated data will be live within two minutes of adding it.
