WebSupport offers IP Anycast

Since January 2011, we have been the first Swedish web host to use a global Anycast network for our clients’ (and our own) DNS services.

As a customer with us, you thus have access to a secure and fast network spread around the world.

 

WebSupport offers an IP Anycast network for its DNS services. Name servers are a prerequisite for web browsing, they are also usually the most vulnerable link. If the few name servers (usually two to four) lowered by a DDoS attack are lowered, no websites linked to them can be reached.

IP Anycast Routing provides global load balancing, redundancy, reduced response time and better distribution which can be an advantage in DDoS attacks, and it is completely transparent to the client (end user). By having multiple networks that dynamically respond to the same IP address, you can dramatically increase performance and availability.

With the help of IP Anycast, each name server IP on WebSupport corresponds to a network of a large number of name servers spread across different geographical locations around the world. DNS requests are then automatically sent to the name server closest to the requesting client.
