Modifying CNAME Records

After a domain name is created, EdgeOne will assign a CNAME address to it. You need to complete the CNAME configuration to enable secure acceleration for the domain name.

Scenario 1: One-click CNAME Addition in NS Mode or DNSPod Managed Mode

In DNSPod managed access mode, domain names support one-click CNAME addition, helping you quickly complete the CNAME configuration.
1. Log in to the EdgeOne console, select the site to configure from the site list and enter the site management submenu.
2. On the left navigation bar, click Domain Name Service > Domain Management to enter the domain name management page.
3. If the current domain name has not yet configured with a CNAME, click One-click Add in the status column.

4. In the pop-up window, after confirming the relevant CNAME information that EdgeOne will operate on, click OK . In the second pop-up window, click OK again to make EdgeOne automatically complete the CNAME configuration for you.

Scenario 2: Manual CNAME Configuration

1. After a domain is added, EdgeOne provides you a CNAME pointed to the EdgeOne node.

2. Go to the DNS service provider of the domain name and add a CNAME record. See below for examples for different DNS service providers.
Tencent Cloud DNSPod
Alibaba Cloud DNS
Godaddy
a. Log in to the DNSPod console. Find the domain to verify in My Domains. Click the domain to enter the domain name configuration page.



b. On the domain name configuration page, click Add Record to add a DNS record for the domain name.


c. Enter the record type, host record, and record value obtained in Step 1.

3. Now, the Status of the domain should be Validated.



Verifying CNAME Records

After you complete the CNAME configuration, EdgeOne automatically detects whether the CNAME configuration has taken effect. In the domain list, if the Status column of the accelerated domain is Activated, the domain is correctly configured and accelerated.



If you have correctly configured the CNAME record, but the status is CNAME unconfigured, this may be caused by the CNAME resolution latency of the DNS provider. In this case, you can manually verify the connection by using the following methods:
Windows
Mac/Linux
Open the command prompt and run the nslookup -qt=cname www.example.com command. Then, check the CNAME information of the domain. If the CNAME information is the same as that provided by EdgeOne, DNS of the accelerated domain has been switched to EdgeOne.


Open the terminal and run the dig www.example.com command. Then, check the CNAME information of the domain. If the CNAME information is the same as that provided by EdgeOne, DNS of the accelerated domain has been switched to EdgeOne.
