For example, you might read an article about how to raise bonsai trees. Once someone knows that, they may also be able to poke around online and find your actual address. Many home invaders keep an eye on social media so they know when homeowners go out of town. Many online services get this information from your IP address and restrict your access to their services. Other companies charge different rates depending on where you live. Essentially, such attacks prevent you from accessing network resources, including a website you visit, online accounts, and even email.
The most common method for such attacks is to flood your address with server requests, overloading and disabling your system with traffic. A DDoS distributed denial of service attack works similarly, only it involves multiple machines so the traffic is even more intense.
Discover personal information about you : Identity thieves are constantly on the lookout for PII personally identifiable information. What is PII? This can include items like your Social Security number, phone number, mailing address, and birthdate, all valuable information for identity thieves.
One sure way to prevent identity theft is to buy one of the best identity theft services. Frame you for crimes : A skilled hacker can use your IP address to impersonate you online, routing activity through your address instead of their own. Ultimately, they could frame you for buying drugs, downloading child pornography, or even creating national security threats. Sell it on the dark web : Not all thieves are looking to cash in by impersonating you. Some are happy just to steal your IP address and sell it on the dark web.
There's no real reward in it for them, so unless they love playing pranks, it would be a waste of time. In 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's. That 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 know.
It'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. 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 neighborhood. 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.
I have experienced this when browsing Wikipedia, I got a notice due to vandalism by an anonymous user based on IP address.
This is an empty threat. I'm guessing this question is relation to this: arstechnica. Then they use the remote access to steal your financial and business data.
It's quite impossible to 'steal' in this specific scenario -- while the BGP scenario given below is plausible, I don't think it's happened in this case. Add a comment. Active Oldest Votes. A few mitigations: ISPs generally filter BGP connections to their customers and only accept specific routes, but there are plenty of unfiltered BGP connections out there I personally had access to one in a prior job Improve this answer.

Gnudiff Perhaps. They would probably have to be in the same area, so they'd be served by the same DHCP server, on the same subnet. There was a case of erroneous BGP-Advertising several months ago, which broke access to a lot of pages for many users.
Which just revealed how incomplete the protections still are in this outdated networking protocol: blog. While this technically answers the question, I imagine the technical details are way too complicated for the OP and even with the disclaimer they might get the wrong idea from this. Sure this is possible and has happened in the past, but only a few larger organisations and states have the capabilities of doing so and it's hard to imagine you'd ever do this to target a single user.
There's absolutely no reason for a normal user to worry about this — Voo. Show 5 more comments. IcaroAugusto IcaroAugusto 2 2 silver badges 4 4 bronze badges. Certainly the likeliest threat vector for an average person.
This answer could be improved by writing with more detail and the proper terms. It's also a bit ESL-like, but I'm not concerned with that. He asked me to help him solve this problem. Neither your ISP nor anyone else can actually tell what you are doing on the Internet.
But they can follow the activity of your public IP address—the one your router uses to access the Internet.
