Set up DNS

To get your users to connect to Lumen servers you need to make updates to DNS. This DNS change will point the traffic to Lumen servers.

Note: This tutorial works with a domain name that contains a prefix, like the www.prefix in www.lumen.com.

Note: If you are working with a site that doesn’t have a prefix please look at bare domain suppport with Lumen.

This section will walk you through the steps needed to add a domain to an existing Lumen environment. For help understanding whether adding a new domain to an existing environment is best for your use case, please contact your Lumen support team.

 

If you wish to set up an entirely separate application for this domain, please see the getting started guide for creating your first application.

Set up the CNAME record

Step 1: Adding the domain

  1. In the set-up console, click DNS in the left-hand menu.
Navigation showing DNS
  1. Click on “Add Domain”, input the desired domain and hit save. 
Add domain

This will configure the Lumen platform to route all requests for your desired domain through this environment’s module stack.

Step 2: Configuring DNS

 

You will need to make the DNS record for the domain you added point to the CNAME record automatically generated for that specific domain for traffic to flow through the Lumen platform.

 

Assume we added www.example.com

  1. Navigate to your DNS hosting provider.
  1. Copy the target CNAME record provided by Lumen.

    The value will be www.example.com.c.section.io
CNAME information from Lumen
  1. Replace your existing CNAME record with the one from the previous step.
  1. Save your changes.

Important: If there is an AAAA IPv6 record setup for the domain, it will need to be removed as Lumen uses IPv4.

  1. Back in the set-up console, click Verify. You’ll see a message that your DNS is correctly configured.

Important: If you have any trouble, contact your Lumen support team.

Note: All domains added to the Lumen platform will generate a unique CNAME record. This CNAME record follow the naming convention domain.c.section.io.
