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 works like this: imagine you have several identical stores in different neighbourhoods. When someone asks for directions to your store, they're directed to the nearest one. Anycast DNS does the same thing with internet traffic: it directs users to the closest server that has the same information about your website. It makes websites load faster because users connect to servers that are physically closer to them, reducing the time it takes for information to travel back and forth. It also helps ensure websites stay online even if some servers have issues because there are backups ready to take over. Overall, Anycast DNS improves speed, reliability, and efficiency for websites and online services.
Routes queries to the nearest server, reducing latency and speeding up response times.
Provides redundancy by automatically redirecting queries to available servers if one fails, ensuring high availability.
Distributes traffic across multiple servers, making it harder for attackers to overwhelm the network and improving resilience against DDoS attacks.
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!

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 64 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.
