An entity is a geographical area that has an ISO two letter country code (ISO 3166). These country codes are included in the Table below for each entity (Cols 8-9). Note that the ISO codes do not always agree with the top level DNS (Domain Name) code(s) used for a particular entity.

Haiti's u entry is based on a ccmail email link. Restricted access or dial-up IP links exist to Lebanon, Senegal, Mali, Burkina Faso, Guinea, and Niger. These are not included in the table.

The Internet standard is usually the same as the ISO-standard (International Standardization Organization), but there are exceptions. Among others Great Britain with uk in stead of gb. In Russia many servers still use su that stands for the Soviet Union.

In column 2 only permanent connections count. Several more countries have Dial-up connections. Many countries also have private FIDONET-connections, these are not counted here.
