What is an IP Address?
Before we delve into the specifics, let’s clarify what an IP address is. IP (Internet Protocol) address is a unique identifier assigned to each device connected to a network that uses the Internet Protocol for communication. It serves two main functions: identifying the host or network interface and providing the location of the device in the network.
There are two main types of IP addresses:
- IPv4: This is the most commonly used IP address format, represented as four sets of numbers separated by periods (e.g., 192.168.1.1). It has the capability to address about 4.3 billion unique devices.
- IPv6: Developed to accommodate the growing number of devices connected to the internet, this format uses eight groups of hexadecimal numbers separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).
In this article, we will primarily focus on how to find both types of IP addresses on your laptop, particularly when using popular operating systems like Windows and macOS.

What is the difference between a public and a private IP address?
A public IP address is assigned to your network by your Internet Service Provider (ISP) and is visible to the outside world. This address allows your network to communicate with other networks on the internet, enabling access to websites and online services. Public IP addresses are unique across the internet and can be accessed by other devices outside your local network.
On the other hand, a private IP address is used within a local network and is not routable on the internet. These addresses are reserved for internal use and help devices communicate with each other in a local environment. Common ranges of private IP addresses include 10.x.x.x, 172.16.x.x to 172.31.x.x, and 192.168.x.x. A router typically assigns private IP addresses to devices within the network while managing the public IP address for outgoing connections.
Can my IP address change?
Yes, your IP address can change depending on several factors. If you are using a dynamic IP address provided by your ISP, it may change periodically. This can occur when you restart your modem/router, when your ISP performs maintenance, or at specific intervals set by your ISP. Dynamic IP addresses are commonly used for residential connections because they are easier to manage and conserve IP address space.
Conversely, if you have a static IP address, it is permanently assigned to your connection and will not change. Static IP addresses are often used for businesses that host servers or require consistent access to remote devices. Users can request a static IP from their ISP, but it typically comes with a higher cost.
Why is it important to know your IP address?
Knowing your IP address can be essential for troubleshooting network connectivity issues. When experiencing connectivity problems, identifying whether your device is correctly assigned an IP address by the router can help diagnose the issue. Additionally, understanding your IP address can assist in identifying network conflicts, enabling you to resolve conflicts between multiple devices on a local network.
Furthermore, your IP address plays a role in accessing certain online services, such as remote desktop applications, web hosting, and gaming servers. For example, if you need to configure port forwarding on your router, you will need to know your IP address to correctly set it up. Overall, having this knowledge can enhance your ability to manage digital security and maintain smooth internet connectivity.
Can I hide my IP address?
Yes, there are several methods to hide your IP address if privacy is a concern. One common way is to use a Virtual Private Network (VPN), which routes your internet traffic through a secure server, effectively masking your real IP address. When using a VPN, websites and online services will only see the IP address of the VPN server, not your actual IP address. This provides an added layer of security and privacy while browsing.
Another option is to use a proxy server, which also hides your IP address by acting as an intermediary between your device and the internet. However, while proxies can be suitable for basic privacy needs, they often do not offer the same level of security as a VPN. Additionally, using the Tor network is an advanced method to conceal your IP address, allowing anonymous browsing by routing your connection through multiple volunteer-run servers around the world.
