Whats the IP ?

                 

IP - Networking

                            The internet protocol address (IP address) is a numerical identifier that is associated with a specific computer or computer network. When computers are connected to the internet, the IP address allows them to send and receive data.

How an IP Address Works


Computers use IP addresses to send and receive data over the internet. The majority of IP addresses are numerical, but as internet usage grows, some addresses have letters added to them which is now being in use IPv6.


IP addresses are divided into four categories: public, private, static, and dynamic. While public and private indicate network location (private being used within a network and public being used outside of a network), static and dynamic indicate network permanency.


A static IP address is one that was created manually rather than being assigned. A static IP address is permanent, whereas a dynamic IP address is assigned by a Dynamic Host Configuration Protocol (DHCP) server and that can change often. The most common type of internet protocol address is dynamic IP addresses. Dynamic IP addresses are only valid for a limited period of time before they expire. Either the computer will automatically request a new lease or it will be assigned a new IP address.


Because each IP address is completely unique to the computer or user to whom it is assigned, it can be compared to a Social Security Number (SSN). Routers will use these numbers to figure out where they're sending information over the internet. They also ensure that the messages are delivered to the correct devices. A router, like a post office, requires an IP address in order to deliver a package to the requested web address.


Example of an IP Address


The term "dark web" refers to online content that is encrypted and not indexed by traditional search engines. Criminals will trade illegal and counterfeit drugs on the dark web's illegal online black market. Many of these transactions are conducted using the online cryptocurrency bitcoin, making it more difficult for authorities to monitor and apprehend those involved.


After a year-long government activity, officers with the Department of Homeland Security pretended to begun traffickers in order to obtain access to the computers of criminals attempting to buy weapons illegally in 2018. This gave them access to IP addresses, which they used to track down the geographical positions of other dark web suspects.


It's not the first time that IP addresses have resulted in arrests. In 2012, police tracked down and charged members of the hacker group Lulzsec using IP addresses. Law enforcement officers were able to uncover the physical addresses of the criminals and apprehend them for their illicit internet activity by using warrants to collect information from the Internet Service Provider (ISP).
