This document describes how to change the CNAME of a domain name.
Note:
This is only required for sites connected via the CNAME. You don't need to do this for sites connected via the NS.
Scenarios
In CNAME access mode, besides adding an acceleration domain name or alias domain, you also need to configure the CNAME record at your DNS service provider before you can direct user access to EdgeOne nodes and make the acceleration take effect.
Directions
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.
b. On the Portfolio page, click the target domain name to go to the Domain Settings page.
c. Click Add to add a DNS record for ownership verification of the domain name.
d. 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.
