How long should the DNS server address be set to?

What is the server address of DNS?

DNS (Domain Name System) is the system used on the Internet to resolve domain names into IP addresses. It enables users to access websites or services by converting the domain name entered by the user into the corresponding IP address.

When setting the DNS server address, there are generally two options: use the default DNS server address provided by the ISP (Internet Service Provider) or manually set a custom DNS server address.

Most users use the DNS server address provided by the ISP by default. This is because the ISP usually provides users with reliable DNS services, and its settings are relatively simple and do not require additional configuration by the user. However, there are some potential issues with using your ISP's DNS servers.

First of all, the DNS server provided by the ISP may be slow, causing users to experience delays when accessing websites. Secondly, the ISP’s DNS server may collect users’ DNS query data, thus affecting the user’s privacy and security. In addition, some ISPs may filter or hijack users' DNS requests, thereby interfering with users' normal Internet access.

In order to solve these problems, many users choose to manually set a custom DNS server address. Here are some commonly used public DNS server addresses for reference:

1. Google Public DNS: 8.8.8.8, 8.8.4.4
   Google Public DNS is a free public DNS service provided by Google. It is widely used Considered stable, high-speed, and reliable. Using these addresses provides faster resolution and greater privacy.
2. CloudFlare DNS: 1.1.1.1, 1.0.0.1
   CloudFlare DNS is a DNS resolution service provided by CloudFlare, the world's leading network security and acceleration service provider. It is known as one of the fastest parsing services in the world, while also offering security and privacy protection capabilities.
3. OpenDNS: 208.67.222.222, 208.67.220.220
   OpenDNS is a very popular public DNS service, mainly used to provide Internet filtering and home security functions. It parses relatively quickly while also providing some additional security and filtering options.

In short, it is very important to choose the appropriate DNS server address, which directly affects the user's Internet experience and security. For most users, using the default DNS server provided by your ISP may be the most convenient option. But if users have higher requirements for speed, security and privacy protection, manually setting a custom DNS server address is a good choice. The above-mentioned public DNS servers such as Google Public DNS, CloudFlare DNS, and OpenDNS are currently popular choices, and users can select and configure them according to their own needs. No matter which method you choose, you should pay attention to updating the DNS server address in time to ensure the normal operation of the DNS resolution service.
