Geolocation of Domains
The Geolocation is performed using the domain ip address, not on the domain itself.
For this purpose, several external web services and ip address free databases are used. All of them are free and legal services, which provide regional information to achieve the graphical representation of the collected domains in a user friendly way.
The regional information is transformed into coordinates using inverse geolocation, these coordinates then placed on a Google Maps map, which shows coordinate information as positional markers.
It's flexibility allows to build layers of lines on top of it.
