The article "Free Domain Name DNS Resolution Services" has introduced several free foreign domain name resolution services. If you are interested, you can take a look. These days, Xiaoz has been trying various DNS resolutions and accidentally discovered ClouDNS.

Founded in 2010, ClouDNS is located in Bulgaria. They provide free DNS hosting services, but the free version only supports 3 domain names and has basic features. There's not much to introduce. This article mainly introduces their paid DNS services, with the lowest package starting at $2/month and powerful features, which is very suitable for individual users.

Getting Started

Registration link: https://asia.cloudns.net (including AFF)

ClouDNS supports a Chinese interface, you can switch to Chinese Simplified in the upper right corner. It is probably machine translation because many pages are still in English. Even the paid packages of ClouDNS support a 30-day free trial. After successful registration, you can visit https://asia.cloudns.net/premium/#trial-52 to experience it.

Anycast DNS

ClouDNS's paid packages support Anycast technology. Anycast DNS is a network addressing and routing method, where data packets from a single sender are routed to the topologically closest node in a group of potential receivers. In simpler terms, if you have multiple resolving IPs for a hostname, Anycast DNS will assign the nearest IP based on the visitor's network situation.

Dynamic DNS (DDNS) Resolution

ClouDNS provides a very user-friendly DDNS resolution service. You can enable it with just one click in the background, and it generates various scripts for you. You can directly access the provided API address or add the address to the scheduled task to achieve dynamic resolution. It's really simple.

URL Forwarding

Using ClouDNS's URL forwarding service, you can set up 301 and 302 redirects to automatically redirect to the target address. However, many domestic DNS vendors require the service to be used in the North Shore, which can be directly set in the ClouDNS backend.

HTTP API

If you are a developer, you naturally can't do without tinkering. ClouDNS provides an HTTP API service with very detailed documentation. You can implement more ideas according to your needs, such as backup IP, failover switching, and other functions.

Others

ClouDNS supports multiple record types, you can set SOA, as well as some that I have seen and haven't seen. Please refer to the screenshots below for details.

Summary

Although ClouDNS has rich features, there are some shortcomings, such as the inability to pause resolution, lack of support for backup IP, and inability to achieve failover switching unless you develop it again through the API. A few months ago, ClouDNS DNS servers seemed to have suffered a large-scale DDoS attack, and the stability needs further observation. Since the paid packages can be used for a trial month, why not give it a try.
