What You Can Do With an IP Address, and How to Hide Yours

With someone’s IP address, you can learn a user’s general location, and disable some parts of their internet browsing device connected to the internet has an IP address, which helps websites identify your third-party programs or services, someone with your IP address could possibly block you from reaching certain you’re concerned about the security of your IP address, consider installing a firewall and Business Insider’s Tech Reference library for more stories.

Every device that connects to the internet has an IP (Internet Protocol) address. The
IP address, which is composed of a series of numbers separated by decimal points, looks something like “198. 169. 0. 100. ” This number is used to help devices talk to each other and exchange data. Your network router has its own IP address, of course, as does every device on your network. But because these identifiers are so important, that means a hacker can potentially use them against you. Here’s what you should know about your IP address, and what it can be used for.
What you can do with an IP addressFirstly: most users won’t have to worry about any of this. It’s unlikely that any hacker would take the time to learn your specific IP address, and manipulate your specific device. There’s no real reward in it for them, so unless they love playing pranks, it would be a waste of fact, every website you visit already knows your IP address — that’s how they know to load on your computer, as opposed to someone else’ said, armed with your IP address, someone has the potential to take certain actions against your network. As such, it’s a good idea to keep your IP private from individuals you don’t could:
Block you from accessing websitesIt’s possible to use your IP address to prevent you from performing certain online activities. The most common example of this is blocking your ability to reach a certain site, or to post messages in forums or the comment section of web sites. In fact, this is the most common way that website administrators ban rulebreakers. It’s often referred to as an “IP Ban. “Your IP address can also be used to block or ban you from playing online games on some gaming services.
Learn your general geographic location Your IP address can reveal your geographic location. In most cases, this won’t be any more specific than your city and state. In rare cases, it could be as specific as your IP address also carries the name of your Internet Service Provider (the company that gives you internet access — think Spectrum, or Xfinity).

While there’s not a lot someone can do with this information, it can be combined with details from other sources to piece together data about your identity.
Perform a Denial of Service AttackKnowing your IP address, a malicious user may be able to perform a Denial of Service (DoS) attack, in which your network is flooded with data. It prevents normal traffic from getting through and overloads the network’s ability to function. However, these attacks are usually directed at large companies or websites — it’s rare that anyone would set up a DoS attack on a regular user.
How to protect your IP addressWhile there are some risks, your IP address alone poses very limited danger to you or your network. Your IP address can’t be used to reveal your identity or specific location, nor can it be used to hack into or remotely take control of your computer. That said, if you’re still concerned, a few simple precautions can help protect and foremost, your network should be protected with a firewall. Most routers have firewalls built in, but you should contact your router manufacturer or internet service provider to learn about your additional protection, you can use Virtual Private Network (
VPN) software. A VPN hides your IP address from all outside users, making it extremely difficult for someone to uncover your IP address or monitor your online activity.
NordVPN is one of the most popular VPN services.

How Many IP Addresses Are Left? Almost None.

How Many IP Addresses Are Left? Almost None.

When a company like Microsoft starts running into some technical problems with IP addresses, you know that trouble is brewing. In early 2015, a network expert at Microsoft said to an audience at a vast networking industry conference, “We’ve been having a hard time. ”
The problem seems to have somewhat crept up on them. What is it? The dwindling supply of the common everyday IP addresses that have been around for decades.
It was going to happen someday.
Nearly all the IP addresses in use today are IPv4, for “version 4. ” The number is a unique code the Internet uses to connect us all. Your IP address identifies both the type of network you’re part of as well as your individual “host” or computer. Every computer that’s online at any one time has a unique IP address. (The exception is small home networks that share the router’s IP address; however, all the individual computers still have a unique connection number. )
If you are on the “” home page (MyIP), you’ll see your current IP address. It can change depending on whether you’re connected at home or some other location.
In any case, years ago the IP addressing system was set up to accommodate millions of IP addresses that might be needed one day. In fact, there are today about 4. 3 billion IPv4-type IP addresses throughout the entire world.
But the Internet has grown—or rather, exploded—over the past 30 years, perhaps far more than anyone ever expected. And now, some experts are predicting that the number of new available IPv4 addresses could dwindle to nothing as early as this summer.
Think of it like the telephone numbers system in the U. S. decades ago, before there were prefixes and area codes. At one point, phone companies realized that they would soon run out of phone numbers, so they created the area code concept to solve the problem. Today, new prefixes are still being introduced to handle all of the numbers needed.
That’s pretty much the same thing for the Internet and the IP addresses we all need if we want to connect—except that the solution isn’t as simple.
Supply and demand.
Microsoft ran into a problem with “private IP addresses, ” which are special addresses that were set aside for companies to use for internal networks. A company like Microsoft can use the same IP address for different company networks and still connect hundreds of computers with no problem.
Millions of these private addresses were set aside in the mid-1990s, but no one could have predicted all the technological advances that would soon begin to drain that supply of private addresses. It caught Microsoft by surprise—their growth in cloud technology and other business products and services gobbled up the available private addresses that had been allocated.
It’s time to be proactive.
Of course, Microsoft isn’t (and won’t be) the only company that will have to address this issue. Facebook had a similar issue with private IP addresses, but they decided to transition to the future of IP addresses—IPv6. That’s the next generation of Internet Protocol addressing, which will supply an incredible number of IP addresses for the entire world.
According to a report in The Wall Street Journal, Facebook “outfitted its public-facing website for IPv6 at an expense that…could cost 7% of most companies’ IT budget. ”
And now that’s what Microsoft is deciding to do. The person in charge of IP addressing for Microsoft said, “…we moved into the action of making the shift from IPv4 to IPv6 so that we didn’t run into problems internally or externally. ”
That’s the right thing to say for a company that’s 1) supposed to be a technology leader and 2) experiencing some embarrassing technical difficulties. However, talk is cheap and implementing IPv6 isn’t, which is likely why they’ve delayed making it a company-wide initiative.
Along the way, however, that solution may cause some problems and headaches.
Everything runs on IPv4.
Any device that connects to an Internet-connected network needs an IP address, and for almost all companies, those IP addresses are still IPv4. For a large company like Microsoft, that means there are thousands of devices they own worldwide that would need to be converted to the new protocol…eventually.
But until all those devices are replaced by new ones configured to IPv6, they’ll continue to be connected by the IPv4 protocols. And if Microsoft’s growth requires them to add more devices, it’s likely they’ll want to use the new IPv6 protocol and not the older version.
Overall, it simply means that “someday” has arrived. As a network architect at Microsoft said at a recent World IPv6 Forum conference for networking engineers, “I’m only interested in IPv6 because I am tired of people trying to get IPv4 addresses out of me that I don’t have. ”
