Help with GeoIP aliases needed

[cfapress]

I'm trying to only permit traffic from the United States to a handful of ports on my pfSense router.

I thought I had it working with GeoIP - North America - List Action = Alias Permit
Combined with my specific firewall rules that reference the pfB_NAmerica_v4 alias

However, in my firewall logs I'm finding IP addresses permitted through. For example, I'm seeing the follow source IP addresses coming through:
216.220.228.202
104.214.115.196
74.101.171.253
None of those IPs, or their related subnets appear in the North America

All other GeoIP countries have nothing selected in the list with a List Action = Permit Both

Clearly I'm doing something wrong. I've tried my best to find manuals for pfBlockerNG online but the results are sparse.

Thanks in advance, Jason

Looking in my NA list I see
216.220.128.0/17

Which would be 216.220.128.0 - 216.220.255.255
So yeah your 216.220.228.202 is in that list.

AH ... yes, indeed my subnetting skills were lacking here.

I resorted to lookups with this tool which helped me better understand what my brain couldn't sort out itself:

Your link to the maxmind database is very helpful. So, thank you for that. Much appreciated. It will come in handy in the future.

Thanks for the prompt response.
