I am writing some code to retrieve IPs from a domain that comes from a querystring. To achieve this, I have used 

Dns.GetHostAddresses(uri);

Which return type is a array of System.Net.IPAddress[]

But I want to write a comment in the code to explain to the developer why a domain such as google for example, may (OK google will) return more than 1 IP address.

Does anyone have a definition or can direct me to a website that has material on this?

Thanks

Its used as a kind of 'load balancer' for DNS queries.

See here for a good discussion:

Is it possible that one domain name has multiple corresponding IP addresses?
