Anycast DNS is a powerful network routing technique that improves your website's performance and availability. It guarantees visitors are connected to the nearest DNS server, resulting in faster response times and improved website availability.
Anycast DNS is a simple concept - you can reach a single destination following many different roads. Instead of having all the traffic go down one route, Anycast DNS utilizes multiple locations that receive queries to the network, but in different geographical locations. The objective here is for the network to find the shortest path for a user to a particular DNS server.
The definition, from a purely technical standpoint, states "Anycast DNS is a network addressing and routing methodology, in which datagrams from a single sender are routed to the topologically nearest node in a group of potential receivers."

Anycast DNS 的運作方式如下:想像您在不同街區有幾間完全相同的商店。當有人詢問前往您商店的路線時,他們會被引導到最近的一間。Anycast DNS 對網際網路流量也做同樣的事:它將使用者導向距離最近且擁有相同網站資訊的伺服器。這能讓網站載入更快,因為使用者會連線到實體距離更近的伺服器,減少資訊往返所需時間。它也有助於確保即使某些伺服器發生問題,網站仍保持在線,因為有備援可隨時接手。整體而言,Anycast DNS 可提升網站與線上服務的速度、可靠性與效率。
將查詢路由至最近的伺服器,降低延遲並加快回應時間。
若其中一台伺服器故障,會自動將查詢重新導向可用伺服器以提供備援,確保高可用性。
將流量分散至多台伺服器,使攻擊者更難使網路不堪負荷,並提升抵禦 DDoS 攻擊的韌性。
Anycast DNS and Unicast DNS are two different approaches to DNS resolution that have distinct characteristics. The Unicast protocol is a relic from the past and it doesn't adequately meet client's needs. It lacks the ability to mitigate DDoS attacks globally, have lower DNS latency across countries or make proper load balancing in multiple locations. Anycast DNS is your ticket for a fast and reliable DNS at the same time!
ClouDNS features Anycast DNS service in our Premium DNS and DDoS Protected DNS Plans. We maximize the speed, minimize downtime and provide our customers with the highest possible SLA for each of our global locations. As a result, our customers have full redundancy and reliability on our network with reduced latency across each continent.

準備升級到 Anycast DNS 服務了嗎?我們讓遷移變得簡單、快速且全程引導。
Now that we've explained the basics and given you a core definition of Anycast DNS, allow us to get into the details. These are some of the undeniable advantages you get when you use the ClouDNS Anycast network:
ClouDNS utilizes 65 POPs ( points of presence ) on our extensive Anycast Network – available for every domain. This has an immediate positive effect on response times as queries are evenly distributed based on geographical source and servers load.
Forget about downtime and performance issues - our Anycast network has multiple geographically dispersed servers that reroute traffic from any POPs when there are issues that impair performance. Our goal is to provide the highest SLA when possible.
Our Anycast Network is a full dual stack network – IPv4 and IPv6 available at each of our POPs.
No matter what day, no matter when, you’re supported around the clock without a day of rest. ClouDNS provides continuous, uninterrupted network monitoring and support. Our Technical Support team is online for you 24/7 by live chat and tickets. We can migrate your zones for free, read more here.
