Managing the Domain Name

The DNS Self-Management portal allows customers to manage their domain names. Customers can manage their domains from a central web portal which allows them to add, edit and delete DNS entries for their domains. Customers should use the supplied credentials to log into the web portal at http://dns.link.bm.

The Home screen after logging in provides an overview of the services available to you. The key area in the menu on the left is the Provisioning menu. From this menu you can manage your domains.

Click on Provisioning > DNS Zones in the menu on the left to display your domain names.

You will have the option to click Edit for the raw text editor or Zone Editor for the preferred GUI editor.

Edit

If you click Edit you will be presented with a basic text editor of your domain's zone file. You should only use this if you are very familiar with BIND syntax. Making syntax errors in the text editor can cause your domain to become unusable and unresponsive. We strongly recommend using the Zone Editor.

After making changes to your domain and reloading your domain, you will be unable to reload your domain for 3 minutes. You will still be able to save any changes but must wait 3 minutes until you can reload the domain and make the changes active.

Zone Editor

The Zone Editor provides a more guided GUI editor for making changes to your domain. In addition it provides syntax error checks and will either auto-correct any syntax errors or warn you before reloading your domain. Click the Add DNS Record button to add a new DNS entry. Click edit to make changes to an existing entry and delete to remove an existing entry. You should not change any of the other settings in the General Settings, Name Server Settings and SOA Settings sections. Press the Save & Reload button to save any changes and make the changes active. Below are some examples of creating some of the different DNS record types.

After making changes to your domain and reloading your domain, you will be unable to reload your domain for 3 minutes. You will still be able to save any changes but must wait 3 minutes until you can reload the domain and make the changes active.

A Record

A records are the most common type of entry and point a host name to an IP address. Enter the full host name in the Name field and the IP address in the Data field.

CNAME Record

CNAME records point a host name to another host name. Enter the full host name in the Name field and the host name you are redirecting to in the Data field.

MX Record

MX records point a domain to a mail server. Enter the domain in the Name field and the mail server host name in the Data field. Additionally enter a number in the MX Preference field. If you have multiple MX records for your domain, the MX Preference indicates the priority and order for which mail server should be selected first. A lower number indicates a higher priority and that mail server should be selected first. A higher number indicates a lower priority and that mail server should be selected last. 

Do NOT enter 0 as an MX Preference. This is often recommended by Microsoft when setting up MX records for Office 365 Exchange Server. Doing so can result in the MX record disappearing and disrupting the delivery of your email. Use a number 1 or higher.

TXT Record

TXT records point a domain to some entered text data. The entered text could be anything and is used for various services such as domain ownership verification, SPF information to prevent email spoofing, providing additional settings for Office 365 Exchange Servers, etc. The format and syntax of the entered text will depend on what service you are configuring it for. Enter the domain in the Name field and the text data in the Data field.
