There are various ways to find your IP address depending on the operating system that your device employs. Since you are on this webpage, you could simply consult the widget at the top of the screen. It displays your IP address as well as some information that can be obtained from that address, such as your physical location. More on that fact later in this article.
The majority of computer networks, including the Internet, employ Transmission Control Protocol/Internet Protocol (TCP/IP) to enable communication between network-attached devices and computers. They are two distinct entities but are often used together, and the term TCP/IP is the de-facto standard for describing the protocols.
Let’s take a little dive into the functionality that TCP/IP provides. There are four layers and each has its own set of protocols. They are:
So the acronym TCP/IP comes from the protocols used in two layers.
IP addresses come in a variety of flavors. Here are the main distinguishing characteristics that differentiate IP addresses.
These two versions of IP are currently used for the purposes of location addressing and identification.
An IPv4 address is comprised of 32 bits and is expressed in decimal format. You are probably familiar with IP addresses that look like this:
There is a limit of 4,294,967,296 unique addresses that can be constructed using the IPv4 protocol.
An IPv6 address uses 128 bits which exponentially increases the number of unique addresses it can create to 340,282,366,920,938,463,463,374,607,431, 768,211,456. Addresses are expressed in hexadecimal format like this:
The main reason that IPv6 is around is that IPv4 cannot supply enough IP addresses for all of the world’s network-attached devices. Though not directly compatible, the two protocols can operate together.
Here is the other big difference in the type of IP address that you might be using when you connect to the Internet. A static IP address will not change between network connections. Your home Internet connection may be a static IP that is tied to your router. Dynamic IP addresses are assigned by your ISP when you connect and can change over time.
There are some business advantages to having a static IP, but in the end, it is just used to connect you to the Internet, so either type will work.
Here is one way of finding your IP address on some of the more popular computing platforms. This is not meant to be an exhaustive list and there may be other ways to obtain the same information.
|Launch the command prompt.|
|Enter the ipconfig command.|
|Your IP address is shown as your IPv4 address in the command output.|
|Open System Preferences.|
|Choose the network panel.|
|Select your connection and click on the advanced button.|
|Click on the TCP/IP tab to display your IP address.|
|Tap on WiFi Network.|
|Tap on the network connection.|
|Your IP address is now displayed.|
|Select Apps -> Settings -> Wireless & networks.|
|Select the network you are currently using.|
|The IP address and other network information will be displayed.|
Let’s take a look at how the devices in your home obtain their IP addresses. Your ISP assigns a public IP address to your router. This address may change over time, although you may be able to obtain a static IP address if you need one. The router then shares this public IP address with all of the computers and network-connected devices in the home.
Each device is assigned a local IP address that allows them to communicate amongst themselves. These addresses are not used when accessing the Internet. All of the devices in your home accessing the Internet through your router will have the same public IP address. In this way, all traffic is sent back to your router and then to the individual device that is using the network.
As long as you are connected to the Internet you probably don’t think much about your IP address. It’s not like you might have to give it to a cab driver to get you home after a long night of partying. You really don’t need to know your IP address except in some configuration scenarios.
But your IP address is important to others. Why is that, you might ask. Well, the answer is that your ISP can track your online movements through your IP address. They can track the websites that you visit, the amount of time you spend there, and the kind of activity you perform when on a particular site.
Perhaps this doesn’t concern you. But tracking your online activity can be used to produce targeted advertising with which you may not want to be bothered. Identifying the sites and activity you are performing may lead to your ISP throttling your connection speed under certain circumstances. And then there is the situation where your ISP blocks you from accessing torrent sites or other geo-regulated websites.
Your IP address can be used to identify where you have been and what you have done on the Internet. Even if you never have any reason to be concerned about this, there is something that just doesn’t seem right about giving anyone this level of information about ourselves.
There are many reasons why you might want to change your IP address. Perhaps the IP address that’s currently assigned to you has been blocked by a website or online service you use. Or someone leaked it online, possibly along with your other personal information, intending to broadcast your identity to the whole world for malicious purposes.
Whatever your reason is, you should never hesitate to change your IP address to protect your privacy or improve your online experience. Listed below are five tried and tested methods that you can easily use without any special skills or equipment.
Often, you can obtain a new IP address by simply restarting your router. This method works because most internet service providers (ISPs) don’t assign static IP addresses to customers because there’s not enough of them for everybody.
Instead, they use the Dynamic Host Configuration Protocol (DHCP) to assign IP addresses dynamically to customers as soon as they connect to the network. When you restart your router, you force your ISP’s DHCP server to give you a new IP address. For best result, disconnect your router from power and leave it turned off for at least 5 minutes. In some cases, you may have to leave your router turned off for 24 hours to get a new IP address, so keep that in mind and plan ahead.
Unfortunately, you won’t always get a new IP address after a router restart even if your ISP really does use HDCP to dynamically assign IP addresses. Why? Because your ISP always gives the same IP address to the same MAC address, which is a unique identifier assigned to your router. Only when your router’s MAC address changes does your ISP’s HDCP server issue a new IP.
To make that happen, you need to log in to your router and manually make the change. Some routers make this easier than others, but certain models don’t let you change your MAC address at all. Because each router is different, we recommend you google the make and model of your router and follow the instructions you find online. You can also use Google to check if your IP address has change by entering “What is my IP?” into the search box.
Some internet service providers are willing to provide customers a new IP address upon request. If you explain the reason why you want a new IP address and don’t encounter a particularly unhelpful customer support specialist, there’s a good chance that you’ll get a new IP address without having to restart your router or change its MAC address. Just say something like, “Hi, a service I’m using blocked my IP address. Could you please change it for me?”
This method works best with smaller regional ISPs that really care about their customers and are willing to take a few extra steps to make them happy. If your ISP refuses to change your IP address, maybe it’s time to consider switching to a different one, which would by itself result in an instant change of your public IP address.
A VPN masks your IP address by routing traffic through a remote VPN server. In this way, you can get around restrictions enforced by your ISP and maintain privacy over your online activity.
To see this in action, take a look at your IP address. Now, fire up a VPN service and connect to a VPN server. When you query your IP address again, you will see it has changed. Now you can surf in anonymity without any prying eyes following you around.
There are many VPN services you can choose from, some free and some not. Generally, free VPN services limit your bandwidth and impose other restrictions on their use. The good news is that paid VPN services cost just a few dollars a month and offer many advanced features that are well-worth paying for.
Tor is an open source network for enabling anonymous communication on the internet. It consists of thousands of nodes spread across the globe. These nodes form a circuit and pass encrypted traffic from its source to its destination without revealing or knowing the source IP address.
To access the Tor network, you need to download Tor Browser, which is a modified version of Mozilla Firefox. Just like the network itself, Tor Browser is free and open source, and it runs on Windows, Linux, and macOS.
