Dynamic asset group show public ips

Can you create a dynamic asset group that only lists public ip address ranges?

There is an ‘IP address’ filter in the Dynamic Asset Group. You could either specify the external ranges or potentially not specify any private ranges to get the external results.

When I look at the filters which one would be useful?

I was thinking of doing ip in is not in the range of and list out all the RFC 1918 ranges to just show public IPs, or would that not work?

That would work.
