Where is the computer with the IP number of the next higher or lower than your own? Looking at all the networked computers in an abstract way this machine is the next or previous song, the one that occupies the position adjacent logic, ie its 'close' on the Internet. Neighbourhood Research is a simple php script written by Carlos Katastrofsky that provides, through the interrogation of the respective database, the identity of the computer adjacent to a given, in case of this ip there are web content. It goes without saying that, as this assignment is not bound by particular controls, the 'neighbors' network users or entities may be opposite or in opposition, without which they know it, creating a fundamental difference with the real world, in which social classes very different (a rural school and an office of financial services, for example) are never adjacent. This use of non-conventional registration database extracts a sense of equality, which is closely linked to the technical procedures, which are able to pick out from a search of the critical data they contain.
