A technique for balancing the load between servers on the Internet that perform the same functions. When a DNS request arrives at a round robin DNS server, it responds by returning IP addresses in rotation. For example, if a website is made up of 10 servers with the same set of Web pages and content, the IP address of the first server is delivered to the first request; then the second address in the list is given to the second request and so on. This is a continuous loop. When the 11th request comes in, the first IP address is once again handed out; the 12th request, the second address, etc. See
