ClusteredNetworks - Anycast DNS Consulting Services

DNS is the life blood of your Internet Domain name. For as little as $100.00 a DDOS attack, can be purchased on the black web. If you are a Web Design or Hosting Company, protecting you and your customers should be of utmost importance.

At one time most hosting providers only had two authoritive DNS servers, then 3, them maybe 5. But still on a Unicast Network. Today upgrading to an Anycast DNS network is a necessity!

If you are still using a unicast DNS network provider you are susceptible to network outages, DDOS attacks and poor latency which effects the speed of all network services for your domain including Web, Email and your VPN's etc.

At Clustered Networks we assist companies, including Web Designers and Hosting companies to migrate their nameservers from a Unicast Network to an Anycast Network. - Unicast vs Anycast DNS

Benefits of moving to a DNS Anycast network.

Increased Reliability:

Anycast improves reliability of a network-based service by the placement of multiple, geographically dispersed servers or clusters using the same IP address. In the event one server or server cluster fails, traffic is simply redirected to another node without having to change IP addresses.

Load Balancing:

Dynamic layer 3 routing of Anycast IP Addresses nicely load balances traffic over different nodes based on geography. If equal cost route paths are visible from one geography, all nodes can be used.

Increased Performance:

Traffic destined for an Anycast node will be routed to the topologically “nearest” node, thus reducing latency between the client and the node. This ensures that client traffic uses a server cluster closest to them wherever they are globally.

DDOS Attack Protection:

Geographically dispersed server clusters operating using the same publicly announced IP address naturally attract attacks to them, thus sinking it closer to the origin. This also significantly improves capacity and also masks the true location of any “real server” proxied by the Anycast address and hidden behind it.

Enhanced Availability:

In the event that an Anycast node becomes unavailable, traffic can simply shift to an alternate node as soon as the routes are withdrawn from the routing table without the need for the client to communicate with a new IP address. With proper back-end route configurations, tunnels and connection state management, there is no degradation of service even while waiting for routes to be withdrawn.

Increased Redundancy:

Instead of have 1 to 3 (or even 5) nameservers, IP Anycast can have dozens of name servers. It is not uncommon to have 50+ name servers in an anycast DNS configuration. For example Route53, Amazon's DNS service currently has 48 at the time of this writing.

Cost Effective:

Implementing DNS Anycast if very cost effective. Clustered Networks works with a number of the top Anycast DNS providers. You choose and we will help you migrate your network to one that will fit your budget.
