How to change your IP address and hide your location
It’s very easy to change your IP address and keep your location and online activity private. All you need is a VPN (virtual private network).
You can use a VPN to switch your IP address and place yourself in a different location. A VPN routes your internet traffic through a secure, encrypted tunnel so that no one, not even your ISP, can see what you’re doing online.
Connecting to a VPN server will make it seem like you are in the same place as the server location. For example, if you are in the U.S. and you connect to a VPN location in the UK, you will appear to be in the UK. If you are in Canada and you connect to a location in Australia, websites and apps will think you are located in Australia.
There are many advantages to using a VPN to shield your IP address:
Keep your real location private.
Encrypt your internet data so you can go online with greater anonymity and security.
Easily switch between virtual locations, ensuring fuller internet experience, unfettered by censorship or other firewall restrictions.
What is an IP address?
An Internet Protocol address (IP address) is a unique number assigned to all devices (such as a computer, tablet, or phone) when they connect to the internet.
IPv4 vs. IPv6 addresses
Two versions of Internet Protocol are now in use, IP Version 4 (IPv4) and IP Version 6 (IPv6). They have two primary functions: identification and location addressing.
The main difference between IPv4 and IPv6 is the number of possible addresses. IPv4 only allows for about 4 billion, because it uses just 32 bits. IPv6 was introduced in 1995 to ensure that the world would not run out anytime soon: IPv6 uses 128 bits, resulting in 3.4 x 1038 possible addresses.
Everyone online has a public IP address
To use the internet, all connected devices must have a public IP address. An IP address allows two devices—the sender and recipient of internet communications—to find and exchange information with each other.
The setup is similar to real-life address systems. For example, if you were to subscribe to a magazine, the magazine distributor (the sender) would need your address to send you (the recipient) your copies. Without your address, the distributors wouldn’t know where to send the magazine.
The same applies to the internet. Without an IP address, two devices would not be able to find and exchange information with each other.
Public vs. private IP addresses
Unlike public IP addresses, private IP addresses are used by private networks to identify and share information among computers and devices (like printers) that aren’t directly connected to the internet.
Each computer or device in your home network has a unique private IP address so it can communicate with all the others, but nothing outside of the local network can see them or establish a connection.
Your router assigns a private IP address to everything on your home network via the DHCP protocol. Certain ranges of numbers are only available for use as a private IP address.
What your IP address can reveal about you and your location
Your IP address reveals some pretty in-depth information about your location:
- ZIP/Postal code
Anytime you visit a website, it can potentially gather even more information about you. By combining your IP address with other information gleaned from metadata, cookies, trackers, and browser-fingerprinting tactics, website owners, marketers, and advertisers can build quite a thorough profile about you.
They can piece together your location, what websites you’re visiting, what you’re interested in, what you're downloading, and who you’re talking to, and then present you with targeted content and advertisements—or sell your data to the highest bidder.
ISPs are privy to even more information. There is very little about you that your ISP doesn’t know. Because you’re a customer, it knows your name, address, phone number, credit card number, bank account details, credit history, and potentially even more. An ISP can also use your IP address to block, redirect, and censor your web activity.
In countries like Australia and the UK, ISPs are actually required to maintain logs of your browsing activity and hand them over to countless government agencies without a warrant. If you’re browsing websites that aren’t HTTPS-secured, your ISP can see the individual unencrypted webpages you’re visiting.
Even if you’re browsing websites that are HTTPS-secured, your ISP can still monitor the domains you’re visiting (but not the individual pages).
