An Internet Protocol (IP) address is like a digital fingerprint for any device connected to a network. Think of it as a unique identification number, similar to a mailing address, that allows your computer, smartphone, or server to communicate on the internet. Since their creation in the 1970s, IP addresses have become integral to how devices interact online. Whether you are browsing the web, streaming videos, or making online purchases, IP addresses are always at work behind the scenes. To delve deeper into the technical aspects, you can explore the Wikipedia page on IP addresses.
How Does an IP Address Work?
Internet Service Providers (ISPs) usually assign IP addresses to devices. As your gateway to the internet, your ISP is responsible for providing your device with an IP address. For instance, if you are a customer of Comcast or Verizon, they assign an IP address to your device when you connect to their network. Your online activity passes through your ISP, which uses your IP address to route information back to your device. While IPv4 has a limited number of available addresses, its successor, IPv6, offers a vastly larger address space. To learn more about the workings of IP addresses, How-To Geek provides a detailed explanation in their article here.
IPv6 vs. IPv4: Key Differences
IPv6 was developed to address the limitations of IPv4. However, because the two protocols cannot directly communicate with each other, IPv4 remains in use. Here are the key differences between them:
-
Address Style: IPv4 uses a numeric format with binary bits separated by dots (e.g., 192.168.1.1), while IPv6 uses an alphanumeric format separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).
-
Address Size: IPv4 addresses are 32-bit, limiting the number of unique addresses. IPv6 addresses are 128-bit, offering a significantly larger address space.
-
Checksum: IPv4 includes checksum fields for error detection, while IPv6 does not.
-
Security: Security is integrated into the IPv6 protocol, whereas IPv4 relies on application-level security measures.
-
Mobile Compatibility: IPv6 is better suited for mobile networks due to its hexadecimal, colon-separated notation.

Sample Address: IPv4 example: 127.0.0.1, and IPv6 example: 2001:0db8:0000:0000:0000:ff00:0042:7879
Both protocols can operate simultaneously on a network.
Finding Your IPv4 Address
Finding your IP address is straightforward. You can use search engines like Google or dedicated “What’s my IP” websites to check your IP address from your computer or smartphone. Searching “My IP” on Google will display your IP address. However, Google usually shows your IPv6 address if your network supports both IPv4 and IPv6. To specifically find your IPv4 address, you’ll need to use an IP lookup website. These sites are designed to detect and display your IPv4 address.
How to Change Your IP Address
It is easier to change your IP address than you might think. Here are several common ways to do it:
-
Change Networks or Reset Your Router: Switching between networks, such as from your home Wi-Fi to mobile data, will change your IP address. Resetting your router forces your ISP to assign a new IP address to your device.
-
Use a VPN: A Virtual Private Network (VPN) is a reliable method to mask your IP address, making it difficult for third parties, including your ISP, to track your online activities. VPNs also provide additional benefits, such as protecting your online identity and providing access to geo-restricted content from streaming services.

Contact Your ISP: You can also request your ISP to change your IP address for you.
-
Use the Tor Browser: The Tor browser assigns a different IP address each time it is opened. Websites visited through Tor will see the assigned IP address rather than your real one.
Your device is assigned either a static IP or a dynamic IP when you connect to the internet. With a static IP address, you use the same address every time you connect. Dynamic IP addresses are temporary and assigned each time a device connects to the network. Static IP addresses, also known as dedicated IPs, can be reserved for specific entities like businesses.
Will My IP Address Reveal My Exact Location?
No, it won’t reveal your exact location. While your IP address can reveal your Internet Service Provider’s registered location and other information, it’s unlikely to pinpoint your precise location. Checking your IP address on different websites may show slightly different locations. However, some details, such as your country and state, can be identified through your IP address. This information is used for various purposes, including content localization and fraud prevention.
