You could know your local and internet Ip

I have this in Work (PasteUpMorph)
	"Report the public IP of this computer
	World reportPublicIP."

	| addrString m s 	stream |
	stream := HTTPSocket httpGet: 'http://checkip.dyndns.com'.
	stream upToAll: 'IP Address: '.
	stream := stream upTo: $<.
	Socket initializeNetwork.
	addrString := stream upTo: $<.
	m := RectangleMorph new
		color: (Color r: 0.6 g: 0.8 b: 0.6);
		extent: 118 at 36;
		borderWidth: 1.
	s := StringMorph contents: 'Public IP:'.
	s position: m position + (5 at 4).
	m addMorph: s.
	s := StringMorph contents: addrString.
	s position: m position + (5 at 19).
	m addMorph: s.
	self primaryHand attachMorph: m.

For local
 Transcript show: NetNameResolver localHostAddress printString

I've looked at some traffic on the list from a few years ago (6-7 years ago) that appeared to indicate there was no way to do this. As far as I could tell, there was a workaround using (running regularly) shell script that would write interface information to a file that could then be scooped up by the image.
