DNS Traffic Protection QPS

To launch a DNS query attack, the attacker uses servers to send a large volume of domain name resolution requests. This consequently puts a heavy load on DNS servers. If a DNS server is forced to handle excessive resolution requests, this will result in domain name resolution timeout errors. Alibaba Cloud DNS's built-in anti-DDoS protection defends over 10 million domain names against DNS query attacks.

Minimum TTL

When the localDNS server receives a resolution request, it sends the request to the authoritative DNS server to obtain the resolution record and keeps the record for a period of time. During this period, if more resolution requests are received for the same domain name, the localDNS server directly returns the record instead of sending the requests to the authoritative DNS server. The time that a record is kept on the localDNS server is known as the time to live (TTL). The shortest cache time for Alibaba Cloud DNS is 1 second, which is appropriate for situations where records are frequently modified or when record addresses need to be urgently switched. This helps users to achieve high-resolution speeds and accelerate DNS change propagation, so users do not have to wait for the TTL to expire.

Subdomain Level

Alibaba Cloud DNS classifies URLs based on domain names. This function uses ly modified or when record addresses t a record is kept on the ecord for a period of time.as second-level domain names. A possible subdomain for the aliyun.com domain name would be a.aliyun.com. The "a" highlighted in red is the subdomain name. Alibaba Cloud DNS allows you to set up to 10 levels of subdomain names.

A Records Count

This is the maximum number of resolution records that can be added under to single host and line.

ISP Lines

This refers to the carrier lines in a Chinese network environment. In order to accelerate access for Chinese Internet carrier users, Alibaba Cloud DNS's authoritative DNS allows you to set different carrier lines (such as default line, China Unicom, China Telecom, China Mobile, or CERNET) based on access sources. The line options are shown below and default line must be set. If you wish to target the Chinese market, you can set this line based on your actual needs. The line options are as follows: Default,China Telecom,China Unicom,China Mobile, CERNET, World Line, Asia, Australia, North America, South America, Europe, and Africa, Australia, New Zealand, Malaysia, UAE, Thailand, Singapore, Vietnam, Japan, Hong Kong, Taiwan, Macau, Myanmar, Maldives, Nepal, India, Saudi Arabia, South Korea, Philippines, Indonesia, Laos, Cambodia, Mexico, Argentina, Canada, United States, Brazil, Switzerland, Spain, France, Russia, and Sweden.

World Lines

This refers to line subdivisions used for international business. You can set resolution record directions based on different access source regions (by continent or by country). If your business scope is international, it’s recommended that you use a world line. If your business only uses one server, you do not have to set line subdivisions and can simply set a single default line for resolution records.

Search Engine Robots

Indexing will not be affected if your website shuts down. Web crawlers may have a certain impact on website access performance. In response, you can use a search engine line to provide a separate resolution address for web crawlers. By setting a search engine line, you can increase the speed and likelihood of crawlers indexing your website.

Change DNS Product Domain

After purchasing the Alibaba Cloud DNS enterprise version, you can access an Alibaba Cloud DNS instance. You must bind this instance to a domain name before you can use the paid DNS service for this domain name. In addition, a single DNS instance can only be associated with one domain name. If your domain name changes, you can purchase a change quota to bind the new domain name.

DNS Global Data Centers

With the paid DNS version, internationally certified BGP data centers currently have nodes deployed throughout the world: US East, US West, Singapore, Hong Kong, Australia, China Zhangbei, and China Hangzhou.The Alibaba Cloud DNS enterprise and free versions have different DNS clusters. The global node deployment of the enterprise version is described above. The data centers for the free version are located in China Shanghai, China Zhangbei, China Shenzhen, and China Hangzhou.

Add Domain

Alibaba Cloud DNS provides resolution service for domain names across the Internet. If you register your domain name with Alibaba Cloud, the Alibaba Cloud DNS system adds your domain name to the Alibaba Cloud DNS console directly. Thus, you can directly use the DNS resolution service for your domain name and do not need to use the "Add Domain" button to add your domain name. If your domain name is not registered with Alibaba Cloud, you must first add it to the Alibaba Cloud DNS console before using the DNS resolution service. You can also use the "Delete Domain" button to terminate the DNS resolution service.

DNS Settings

These settings allow you to add, modify, delete, suspend, and enable records. Resolution records can be A records, MX records, CNAME records, NS records, TXT records, AAAA records, and SRV records. Please refer to the product manual for details about the record types and their settings.

Domain Name Resolution List

This list contains all the domain names for which you can manage resolutions. These domain names can come from one of two sources: If you have registered your business domain name on the Alibaba Cloud international site, this domain name is automatically added to the domain name resolution list and you will be eligible for free resolution services. If you register a domain name with a third-party domain name service provider, you must add the domain name to the Alibaba Cloud DNS console.

VIP Product Management

This function is only available with the enterprise version of this product. It lists the DNS instances that you can renew or upgrade, bind a domain name, and change the domain name.
