If your company uses multiple Alibaba Cloud accounts, you may need to manage domain names that are effective across these accounts. To do this with internal DNS resolution, you would normally need to add the same internal authoritative domain name to each account and set its effective scope. This process is complex and inefficient for operations and maintenance (O&M) engineers. To simplify this, Alibaba Cloud DNS lets you set the effective scope of a domain name across multiple accounts.
Rules
Billing: When you set an effective scope across accounts, charges are billed to the account that manages the internal authoritative domain name.
Usage: Only Alibaba Cloud accounts can set the effective scope of a domain name across accounts. RAM users cannot perform this operation. You can link only accounts that are on the same site. For example, you can link two accounts on the China site (aliyun.com) or two accounts on the international site (alibabacloud.com). You cannot link an account on the China site to an account on the international site.
Procedure
On the Internal Domain Name Resolution (PrivateZone and Self-built DNS) page, click the Internal DNS Resolution Unified Management button.
In the dialog box that appears on the right, click Add Alibaba Cloud Account.
In the Add Alibaba Cloud Account dialog box, enter the logon email or username of the other account and click Send Verification Code. The verification code is sent to the email address and mobile phone number that are associated with the account.
After the account is authenticated, the newly added Alibaba Cloud account appears in the Internal DNS Resolution Unified Management Settings dialog box.
On the Internal Domain Name Resolution (PrivateZone and Self-built DNS) page, click the Internal Authoritative tab, and then select User Domains.
On the User Domains page, find the domain name that you want to manage and click Scope Settings in the Actions column.
On the Scope Settings page, in the Effective In Alibaba Cloud VPC section, select a VPC under Linked Account. Then, click OK.
NoteOn the Scope Settings page, when you configure the Effective In Alibaba Cloud VPC setting, you can also click + Unified Management Of VPC Internal DNS Resolution (Cross-Alibaba Cloud Account) to associate VPCs across accounts.
After an account is linked, the VPCs in the linked account are not retrieved in real time. If a VPC cannot be found in the linked account, wait for one hour and then try again.
