Overview
Log on to the Alibaba Cloud DNS console. On the Authoritative Domain Names tab of the Domain Name Resolution page, you can view the status of Domain Name System (DNS) servers in the IP Address of the DNS Server column. The following table describes four states of DNS servers.
DNS server state | Description |
Failed to Obtain DNS Settings | Alibaba Cloud DNS fails to obtain the DNS settings of the domain name. Possible causes:
|
Not Use Alibaba Cloud DNS |
|
Check Time Out | The query for DNS server information timed out due to network issues or other uncertain reasons. In this case, you can query the information after you refresh the page a few minutes later. |
Normal | The DNS servers are provided by Alibaba Cloud DNS. |
Failed to Obtain DNS Settings
In most cases, the resolution of a domain name is suspended by the domain name registrar because real-name verification on the domain name is not complete. You cannot resolve this issue in the Alibaba Cloud DNS console. You need to contact the domain name registrar to troubleshoot the issue.
(1) Check the status of the domain name
If your domain name is in the Clienthold state or the Serverhold state, the domain name is locked. A domain name may be locked in the following scenarios: 1. You have not completed real-name verification on the domain name. 2. The usage of the domain name violates anti-abuse policies.
If a primary domain name is in the normal state but Failed to Obtain DNS Settings is still displayed in the IP Address of the DNS Server column, the main reason is that the detection of DNS server status is regularly performed and notification is asynchronously sent. Therefore, we recommend that you refresh the page after 5 minutes when the data is updated.
(2) Check whether real-name verification on the domain name is complete
The domain name is locked by the domain name registrar because real-name verification on the domain name is not complete. Check whether real-name verification on the domain name is complete in the Domains console. The resolution of the domain name fails if real-name verification on the domain name is not performed, the domain name is being verified, or the domain name fails to pass real-name verification.
If real-name verification is complete but the domain name is still locked, you need to wait for two to three days until the domain name is unlocked and can be resolved.
If a subdomain name is hosted by Alibaba Cloud DNS and Failed to Obtain DNS Settings is displayed in the IP Address of the DNS Server column, you must add two name server (NS) records for the primary domain name and point the DNS servers of the subdomain name to the DNS servers assigned by Alibaba Cloud DNS.
If NS records are configured for the primary domain name but Failed to Obtain DNS Settings is still displayed in the IP Address of the DNS Server column, the main reason is that the detection of DNS server status is regularly performed and notification is asynchronously sent. Therefore, we recommend that you refresh the page after 5 minutes when the data is updated.
Not Use Alibaba Cloud DNS
The following section describes multiple common scenarios.
Scenario 1: You do not use Alibaba Cloud DNS
The DNS resolution service that you use is not provided by Alibaba Cloud DNS. This means that the DNS servers configured at the domain name registrar are not the DNS servers assigned by Alibaba Cloud DNS. If you want to use Alibaba Cloud DNS, you need to migrate DNS records added for your domain name to Alibaba Cloud DNS. For more information, see Smooth domain name migration.
If you have changed the DNS servers but Not Use Alibaba Cloud DNS is still displayed in the IP Address of the DNS Server column, the main reason is that the detection of DNS server status is regularly performed and notification is asynchronously sent. Therefore, we recommend that you refresh the page after 5 minutes when the data is updated.
Scenario 2: Paid DNS servers are configured for the domain name but the domain name is not bound to a paid instance
You have already used Alibaba Cloud DNS and paid Alibaba Cloud DNS servers are configured at the domain name registrar. However, the domain name is not bound to a paid instance in the Alibaba Cloud DNS console. You can use the following two methods to resolve the issue:
Method 1: Upgrade the instance bound to the domain name to a paid instance in the Alibaba Cloud DNS console
For more information, see the Upgrade an instance section of the Upgrade, downgrade, bind, or unbind instances topic.
Method 2: Change the DNS servers to the DNS servers assigned by Alibaba Cloud DNS at the domain name registrar
For more information, see Change DNS servers.
Scenario 3: DNS servers have been upgraded to paid DNS servers
You already use Alibaba Cloud DNS and the DNS servers configured for the domain name already have been upgraded to paid DNS servers in the Alibaba Cloud DNS console. However, the DNS servers configured at the domain name registrar are free Alibaba Cloud DNS servers, you need to change the DNS servers to the DNS servers assigned by Alibaba Cloud DNS at the domain name registrar. For more information, see Change DNS servers.
If a subdomain name is hosted by Alibaba Cloud DNS and Not Use Alibaba Cloud DNS is displayed in the IP Address of the DNS Server column, you must add two NS records for the primary domain name and point the DNS servers of the subdomain name to the DNS servers assigned by Alibaba Cloud DNS.
If you have added NS records for the primary domain name but Not Use Alibaba Cloud DNS is still displayed in the IP Address of the DNS Server column, the main reason is that the detection of DNS server status is regularly performed and notification is asynchronously sent. Therefore, we recommend that you refresh the page after 5 minutes when the data is updated.
Check Time Out
The query for DNS server information timed out due to network issues or other uncertain reasons. In this case, you can query the information after you refresh the page 5 minutes later. The resolution of the domain name is not affected.
Normal
Scenario 1: The DNS servers configured for the domain name are consistent
You already use Alibaba Cloud DNS, and the DNS servers configured at the domain name registrar are consistent with the DNS servers assigned by Alibaba Cloud DNS.
Scenario 2: You already use Alibaba Cloud DNS but the domain name is resolved as expected by DNS servers that are not assigned by the system
You already use Alibaba Cloud DNS, but the DNS servers configured at the domain name registrar are not DNS servers assigned by Alibaba Cloud DNS. However, the DNS servers configured at the domain name registrar are of the same edition as DNS servers assigned by Alibaba Cloud DNS.
Even if the DNS servers are in the Normal state, the resolution of the domain name does not necessarily take effect. If you need to check whether the DNS resolution takes effect, see Check whether the DNS records take effect.
