Set up DNS

For Lumen® Application Delivery Solutions, you need to update your DNS to get your users to connect to Lumen. This DNS change points 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. If you are working with a site that doesn’t have a prefix please look at bare domain suppport with Lumen.

Follow the instructions below 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, contact your Lumen support team.

 

Need to set up an entirely separate application for this domain? Review 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 (on the left menu).
  1. Click Add Domain, input the desired domain, then click Save.

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

Step 2: Configuring DNS

 

Now for the domain you just added, you need to point the DNS record to the CNAME record automatically generated for that specific domain so the traffic flows through the Lumen platform. In this example, we'll assume you added the domain 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.)
  1. Replace your existing CNAME record with the one from the previous step, then save your changes.

Important: If you have an AAAA IPv6 record set up for the domain, you need to remove it. Lumen uses IPv4.

  1. Back in the set-up console, click Verify.

    A message appears to confirm that your DNS is configured correctly.

Note: All domains you add to the Lumen platform will generate a unique CNAME record following the naming convention domain.c.section.io.
