What Is An IP Address?

"IP" stands for "Internet Protocol." And “protocol” here refers to the connectivity regulations and guidelines that govern computer networks.

The "address" part of IP address refers to a unique set of numbers linked to all your internet activities.

Putting all this together, an Internet Protocol address is a string of unique numeric identifier separated by periods and carried by every device in a network. This includes every single computer, router, modem, printer, switch, and any other device that is part of a TCP/IP-based network.

This address makes up the core component upon which the networking architecture is built and no network exists without it.

An IP address is not something you sign up for; once you're online, you're automatically assigned an active IP address by your Internet Service Provider (ISP). An active IP address is necessary for you to access the internet.

What Are The Importance Of IP Address?

They are used for interface identification for a network of devices and they also serve to provide a location of these devices. Given that IP addresses are unique identifiers, they empower computers to send and receive information to and from specific computers in a given network. This makes it possible, among other things, for computers from different networks to find each other, connect smoothly, and share information.

How Many Version And Type Of IP Address?

There are typically two versions of IP addresses — Internet Protocol Version 4 (IPv4) and Internet Protocol Version 6 (IPv6).

Internet Protocol Version 4 consists of a 32-bit number and was the first to be designed. It is classified into different classes ranging from class A to class E.

On the other hand, Internet Protocol Version 6 is a 128-bit IP address and was created to take the load off IPv4 which had become proliferative and somewhat jaded as a result of the fast growth of the internet.

Also, there are two types of IP addresses — private and public.

Private IP addresses are static and reusable in nature and are preserved by the Internet Engineering Task Force. They don't change except as a result of network administration. They serve as a permanent Internet address for your corporate or local area network.

Specifically, these include addresses beginning with “10.”, “172.16.”, and “192.168.”

Known as trap streets, these imaginary roads exist purely as figments of an overactive legal imagination

This is the strange fate of digital mapping products in China: there, every street, building, and freeway is just slightly off its mark, skewed for reasons of national and economic security.

--

As stated in the “Surveying and Mapping Law of the People’s Republic of China,” for example, mapping—even casually documenting “the shapes, sizes, space positions, attributes, etc. of man-made surface installations”—is considered a protected activity for reasons of national defense and “progress of the society.”  Those who do receive permission must introduce a geographic offset into their products, a kind of preordained cartographic drift. An entire world of spatial glitches is thus deliberately introduced into the resulting map.

The central problem is that most digital maps today rely upon a set of coordinates known as the World Geodetic System 1984, or WGS-84; the U.S. National Geospatial-Intelligence Agency describes it as “the reference frame upon which all geospatial-intelligence is based.” However, as software engineer Dan Dascalescu writes in a Stack Exchange post, digital mapping products in China instead use something called “the GCJ-02 datum.” As he points out, an apparently random algorithmic offset “causes WGS-84 coordinates, such as those coming from a regular GPS chip, to be plotted incorrectly on GCJ-02 maps.” GCJ-02 data are also somewhat oddly known as “Mars Coordinates,” as if describing the geography of another planet. Translations back and forth between these coordinate systems—to bring China back to Earth, so to speak—are easy enough to find online, but they are also rather intimidating to non-specialists.
