What Are Huawei Cloud DNS Servers?

Huawei Cloud DNS Servers

DNS servers are deployed in multiple AZs around the world so that it can respond to queries for domain names at the lowest latency and support anycast in some regions.

The following are Huawei Cloud DNS servers:

• ns1.huaweicloud-dns.com: DNS server for regions in the Chinese mainland
• ns1.huaweicloud-dns.cn: DNS server for regions in the Chinese mainland
• ns1.huaweicloud-dns.net: DNS server for countries or regions outside the Chinese mainland
• ns1.huaweicloud-dns.org: DNS server for countries or regions outside the Chinese mainland

After you create a public zone on the DNS console, an NS record set is automatically generated for this zone, and its value is the four DNS servers.

Suggestions on DNS Server Setting

Because the outbound bandwidth from the Chinese mainland is limited, network latency increases when end users access a network outside the Chinese mainland.

To reduce network latency, you can follow the suggestions below to set the NS record set for each public zone:

• If your end users are mainly in the Chinese mainland, use ns1.huaweicloud-dns.com and ns1.huaweicloud-dns.cn.
• If your end users are mainly in countries or regions outside the Chinese mainland, use ns1.huaweicloud-dns.net and ns1.huaweicloud-dns.org.
• If your end users are all over the world, use all four DNS servers.

Procedure for Setting DNS Servers

1. Modify an NS record set.

   Set the DNS servers by modifying the NS record set on the Record Sets tab.

   1. Go to the Public Zones page.
   2. In the public zone list, locate the zone for which record sets you want to modify and click the domain name.
   3. On the Record Sets tab, locate the NS record set that was automatically generated by the DNS service and click Modify under Operation.

The NS record value of some public zones is set to ns1.hwclouds-dns.com and ns1.hwclouds-dns.net. These addresses are used by Huawei Cloud DNS to provide resolution services for users in earlier versions and will be removed soon.
