What is the Firefall to the host servers, anycast for DNS servers is the good old days, where hackers attacked the CIA and the Pentagon, is over. Today, any website can become the target of hackers and script-kids. Numerous providers were affected last year by distributed denial of service attacks on DNS servers. The year’s results in connection with recently reported power outages should give seriously to think all companies with an Internet presence at Rollingstone.com or Comcast”, Cricket Liu, Vice President of architecture at Infoblox and author commented on various book titles. Despite the years in which weak points of the domain name system (DNS) described name and published appropriate mains failures in connection with DNS, many companies DNS security lightly.

We have not nearly reached, what is required to stop hackers, to wreak havoc.” If the website of your company still unaffected – she was that could be next to the at times is forced by the network. It can be however with anycast name servers do much themselves to improve the security of your domains. Anycast is a technology where the same IP address in multiple geographic locations is available at the same time. BGP, the global routing protocol of the Internet, ensures that requests to the topologically closest instance are carried out. For even more details, read what Ali Partovi says on the issue. This reduces the latency in the DNS query, and the load is distributed over the different “nodes” (locations). In case of an attack on the name server network, only the instance of the attack “next” is affected, so that normal operation on the remaining nodes can continue to run. Through the aggregation of the nodes on a single IP address, an anycast network compared to multiple unicast instances saves also “space” in the DNS packets, because it consists of the anycast network only as a single NS record in the delegation appears currently 6 active (and 3 planned) globally distributed locations: Brussels, Belgium Dublin, Ireland Frankfurt, Germany of new York City, NY, United States Seattle, United States Warsaw, Poland Vienna, Austria (scheduled for end 2011) Los to jellies, CA, United States (scheduled for end 2011) Singapore, Singapore (scheduled for end 2011) the corresponding “control” servers are in Vienna and Salzburg (Austria). The locations of the anycast nodes are continuously expanded all the sites are redundantly laid out and designed for a query load of 100,000 queries per second, and location. The locations are typically located in close proximity to the local Internet Exchange, and thus guarantee lowest latency. Domains with anycast name servers are not only safer and more quickly accessible, but get one also tends to be higher PageRank on Google because the speed when you call of a Web site with einfliesst in the page rank from Google.
