If you renew your domain name after it expires, it usually takes 24 to 48 hours for the domain name to be restored, and this process cannot be accelerated. We recommend that you renew the domain name before it expires. The following section describes two common scenarios in which domain names are renewed after expiration.
After a domain name expires, the addresses of the Domain Name System (DNS) servers are changed to expirens3.hichina.com and expirens4.hichina.com in both scenarios.
Scenario 1: The domain name that you renew is registered with Alibaba Cloud, and the DNS service is Alibaba Cloud DNS.
Free edition
If you use the free edition of Alibaba Cloud DNS, DNS resolution will be resumed after the time-to-live (TTL) period. In most cases, the TTL period is 10 minutes.
Paid editions
If you use a paid edition of Alibaba Cloud DNS, the DNS resolution over the basic lines supported by the free edition is resumed after the TTL period. In most cases, the TTL period is 10 minutes. However, the DNS resolution over the lines or the custom lines supported by the paid editions is globally resumed after up to 48 hours. This process cannot be accelerated.
Basic lines of the free edition
Default line, China Unicom, China Mobile, China Telecom, China Edu, lines outside the Chinese mainland, Baidu, Bing, and Google
Lines of paid editions:
The intelligent DNS resolution lines except for the preceding basic lines. For more information, see Supported intelligent resolution lines.
Scenario 2: The domain name that you renew is registered with Alibaba Cloud, and the DNS service is provided by a third-party DNS service provider.
If the domain name expires, the addresses of the DNS servers are reset to expirens3.hichina.com and expirens4.hichina.com. After you renew the domain name, the addresses of the DNS servers are changed from expirens3.hichina.com and expirens4.hichina.com to the addresses provided by the current DNS service provider. In most cases, you need to wait for up to 48 hours until DNS resolution is globally resumed. This process cannot be accelerated.
To prevent business unavailability caused by a long-time interruption in DNS resolution after DNS servers are reset upon domain name expiration, the domain name registry nodes return the addresses of DNS servers of the free edition of Alibaba Cloud DNS in recursive resolution. You can go to the Alibaba Cloud DNS console to add DNS records to keep the DNS records as same as those provided by the DNS service provider. DNS resolution can be resumed after the TTL period. In most cases, the TTL period is 10 minutes.
