Hi Peter, Nice observation about name resolving.
On my MacBook, if i switch off the wifi, then 7 addresses are returned 4 for the en0 and 3 for lo0. Seems overkill to use all of them and the sub-interefaces, if any. I agree with Doug, selecting the first interface's MAC address is probably sufficient. Paul.
