protocol-auara.js line 48 errors if more than 1 IP address on interface

[DeadEnded]

Recently after restarting Node-Red my system would not come up. I have explain the findings here, so I won't write it all out again.

Summary - it appears if you have more than one IP address on your system, protocol-auara.js errors on line 48 when trying to setup multicast_address. I was testing something on my system forgot to remove a second IP I had put in and this caused the failure. This is probably an edge case - but wanted to share my findings in case it helps anyone else - or can lead to a code fix to prevent such issues.

Thanks, DeadEnd
