dig returns ip addresses in differing order?

Question

Pretty basic question here - when I run the command dig mx1.hotmail.com +short to get the ip addresses of one of hotmail's mail servers, they return the same list with a different order every time. I was wondering why?

This is called round-robin DNS.

It allows some load-balancing by distributing the load on different servers.
