I don't know about _requirement_, but I have used this option as poor 
man's way to implement geographically local IP addresses
- to anyone return topologically closer IP addresses first, others next.

I found it especially nice because it doesn't matter which service are we 
using - if there are multiple IP's for _anything_, return topologically 
closer first.
