Hi, based on WAF FAQ: https://aws.amazon.com/waf/faqs/
How accurate is your GeoIP database?
The accuracy of the IP Address to country lookup database varies
by region. Based on recent tests, our overall accuracy for the IP
address to country mapping is 99.8%.
You also have to remember that some corporations have a global single internet access even if their branches are in multiple countries: all internet traffic originates from this single place and is seen as such on the internet even if staff from all over the work uses it.
Also, systems like Tor: https://en.wikipedia.org/wiki/Tor_(network) will "muddy the water"
So, think about all those possible circumventions when you implement geolocations-based rules.
Hope it helps!
Didier

Thank you for your prompt response. If we consider countries like Malaysia, Singapore, Brunei, and the Maldives, which are relatively small in size, is the geolocation accuracy still 99.8%? Has aws determined the specific accuracy level for each of these countries?
