Personally, I'd use:

  echo "My IP address is: `hostname -I`"

However... the hostname command might not be the best all-rounder, but 
some something like a personal computer it might be fine, but e.g.:

gordon @ watertower: hostname -I 192.168.1.2 192.168.254.1 81.31.100.110 
81.31.100.109 81.31.100.106 192.168.247.1 81.31.100.105 
2001:4d48:ad51:8901::1 2001:4d48:ad51:8902::1 2001:4d48:ad51:8900::1

Now which one do I pick...

Happy new year, everyone.
