Anycast DNS is a really useful service that can help your business. It makes surfing the web much faster and more efficient. So, let’s explore that a little more.
Anycast DNS – detailed explanation
Most DNS providers provide Anycast DNS service as an optional feature. It is a helpful tool for traffic routing that allows websites to provide content rapidly. This is made feasible by the multiple nameservers that store a specific identical IP address.
Each of these servers is located in a different geographical area in order to be closer to potential users. As a result, DNS queries are answered much faster, and the user experience is enhanced. In addition, the closest and available server will respond to the user’s request. As a result, the Anycast DNS service reduces latency to virtually zero, and your clients will not have to wait long to access and explore your website.
Furthermore, even if the nearest server is unable to respond, such as when it is under maintenance, your website will remain accessible. DNS resolution is completed quickly due to selecting the fastest path.
Different Routing methods
To send or receive data, you have a few alternatives. However, each of them has its own set of requirements implemented in various settings.
- Anycast is comparable to Unicast in many ways. There is one significant difference, however: there are several hosts. As a result, the inquiry will be forwarded to the closest host.
- Unicast is a one-to-one communication system. This is the most fundamental technique in which all traffic is sent to a single site.
- Broadcast is a term that most people are familiar with from television and radio. The data is carried from one point to all in this system.
- Multicast is one-to-many as well, though not to everyone. The traffic is only of interest to a small group. So, type is helpful if there are no local nameservers.
Benefits from using it
As you can see, Anycast is a convenient service. So here are the three reasons why you should choose it if you are still considering implementing it for your business.
- The first one is that it is simple to configure. It’s easy to set up because you need to configure it on one server. Additionally, similar changes can be made across the entire network.
- The second reason why you should choose it is the improved uptime. A server can fail, but the likelihood of a group of servers failing at the exact moment is extremely unlikely. As a result, your website will have improved uptime, and your users will be able to access it at any time. In addition, the response time is faster. When your servers respond quickly, the waiting time is significantly reduced. Few potential customers will abandon your website.
- And the last one is better security. DoS and DDoS attacks might use many ways, but the common thread is that they use large amounts of traffic as a weapon against flood victims. Typically, the technology used to prevent and guard against such attacks is complex and costly. Given that Anycast DNS is excellent for load-balancing, the anomalous traffic might be distributed over the network without causing an issue. Your security will be much stronger if you use this excellent strategy. Don’t undervalue the security of your website.
Conclusion
Anycast DNS, in general, is a method of keeping traffic local. You route it to the nearest instance, ensuring that your clients receive quick and dependable service. Furthermore, it is simple to set up and will boost your networking. So it is definitely worth a shot!
