IP Addresses and What they do

March 21,

An IP address is a series of numbers that identifies any device connected to the internet. It's like a phone number for your computer or phone, allowing it to communicate with other devices on the internet. The term "IP" stands for Internet Protocol.

There are two types of IP addresses: IPv4 and IPv6. IPv4 is the older version and consists of four sets of numbers separated by periods, while IPv6 is the newer version and consists of eight sets of numbers separated by colons. Both types work the same way.

When you connect to the internet, your device is assigned an IP address by your internet service provider (ISP). This IP address is used to identify your device and route internet traffic to it. Every time you visit a website or use an app, your device sends a request to the server hosting the website or app. The server then responds by sending the requested data back to your device using its IP address.

IP addresses are essential for routing data on the internet. Without them, devices would not be able to communicate with each other. They also allow websites to track visitors and provide personalized content based on their location.

Your IP address can reveal your general location and the type of device you are using. This is because ISPs assign IP addresses based on geographic regions and device types. However, they do not reveal your exact location or personal information.

IP addresses can be static or dynamic. A static IP address is one that does not change and is assigned to a device permanently. This type of address is often used for servers and other devices that require a fixed address. Dynamic IP addresses, on the other hand, are assigned temporarily and can change each time a device connects to the internet. This is the most common type of IP address used for home internet connections.


In addition to IP addresses, there is another important term to understand when it comes to internet communication: DNS, or Domain Name System. DNS is a system that translates domain names (like into IP addresses. When you type a URL into your web browser, the DNS system looks up the IP address associated with that domain name and sends your request to the server hosting the website.

In summary, an IP address is a unique identifier assigned to every device that connects to the internet. It allows devices to communicate with each other and enables data to be routed across the internet. IP addresses can be static or dynamic and are used for security purposes such as blocking access from malicious devices or regions. They also allow websites to track visitors and provide personalized content based on their location. DNS is another important system that translates domain names into IP addresses to enable communication between devices on the internet.
