IP Address
IP addresses are used at layer 3, which means computers and devices all over the Internet use IP addresses for sending and receiving data, no matter which network they are connected to.
What is an IP Address?
An IP address is like a digital fingerprint for your computer or device. It's a unique identifier that allows other devices on the internet to find and communicate with you.
It's like the address of your house, telling people where to send their mail or visit you in person, but in the digital world.
IP addresses are made up of a series of numbers separated by periods, like 192.168.1.1. Each number represents a different part of the address, and together they form a unique code that identifies your device on the internet.
How does it work?
Internet Protocol address (IP) is a Layer 3 address for computers, which allows computers in different networks to easily find each other.
So you can send a ping to an IP address right from your terminal to start a connection with them.
Let's form a connection with NASA with their IP address using our terminal. Open your terminal using:
Press Command + Space Bar on your Mac keyboard (alternatively, press F4) Type in “Terminal” When you see Terminal in the Spotlight search list, click it to open the app.
IP stands for “Internet Protocol”, including IPv4 and IPv6. All IP packets include their source and destination IP addresses in their headers, just as a piece of mail has a destination address and a return address.
IP addresses are used at layer 3, which means computers and devices all over the Internet use IP addresses for sending and receiving data, no matter which network they are connected to.
Layer 3 is where you can also find routers in the galaxy, that look for the most efficient communication pathways for packets also known as payload.
