Describe anycasting and explain how an anycast address is located?

What will be an ideal response?


Anycasting starts by giving a number of computers (or clusters of computers) the same IP address. Then routers (in the case of DNS, only the biggest Tier 1 Internet routers) use Border Gateway Protocol (BGP) to determine which computer in the cluster is closest. When that router gets a packet addressed to that IP address, it sends it only to the closest root DNS server, even though it may know where others are located. That is an anycast address.
