Every device linked to a network that utilises Internet Protocol as its communication protocol has been given an IP address, which is a lengthy string of numbers; it serves as the equivalent of your home or office mailing address in the digital world.
According to how Internet Protocol operates, data is sent over the network in distinct elements called packets. Each packet contains a header that contains information specific to that packet, as well as the majority of the data the sender is attempting to deliver.
The IP addresses of the device which sent the packet and the device to which it is being sent are among the various pieces of information kept in the packet header. This information is used by routers as well as other network infrastructure to guarantee that packets reach their intended destinations.
