-## Women Empowerment in Zanzibar
+## Note
 
-Send a little karma down the way and support women empowerment in Zanzibar by
-helping to [fund the local production of reusable female hygiene
-products](https://www.gofundme.com/f/women-empowerment-in-zanzibar). A very
-dear friend of mine runs the project. They were already able to buy hundreds of
-educational books. Sometimes, it takes so little to make a huge impact. If
-you'd like to thank me or support this work, donate. Additionally, any current
-and future sponsoring of my work via GitHub or other channels will flow one
-hundred percent to the NGO.
+There are more than a dozen commercial IP geolocation database providers, and
+the accuracy of each provider is different. They get IP address information
+from the RIRs, but the assignment changes regularly as some companies release
+unwanted IP addresses and others obtain a new block of IP addresses.
+
+The blocks of IP addresses assigned to many companies can, in turn, assign them
+to their users however they want without geographic boundaries. This makes
+pinpointing geolocation of an IP address rather difficult. The accuracy of
+geolocation data differs by provider. You can generally expect a 95% to 99%
+accuracy for the country level. The more granular you get, the less precise the
+data becomes.
+
+This projects downloads the information directly from the local RIRs and is as
+accurate as the data provided. More often than not, the country attached to an
+IP range is the one the registering company is located in. There is no reliable
+way to determine the physical location of any IP without tracing it separately.
