What If Someone Knows My Ip Address

When you go online through your home computer or mobile device, your Internet Service Provider (ISP) creates a 10-digit unique “name” for your computer. This “name” is based on info like what country you’re in, whether your ISP is private or belongs to a government organization, your type of network and other technical details.

Most people (and maybe you) know their IP address is a digital address of some sort that helps the Internet deliver content to your computer. And perhaps you know that 99% of the time, no one else knows or cares to know what your IP address is. But there’s more you need to know. See, your IP address is something like a beacon on the Internet. If your IP address is known, then people can ping your computer. If too many computers ping your computer, it could cause a meltdown, which is a potential fire hazard. If you really thing someone. If you stumbled upon this because you are hosting a server and your dynamic IP address makes it hard for people to connect to you, check out a Dynamic DNS service such as noip.com. Some people (and typically businesses) have what's called a static IP address. While a dynamic IP address may change, a static IP address does not. Hey there Ketchup! My apologies, but number 1! Don't name the shame on the Forums. It is in violation in the Forum Policy. You do NOT need to contact Xbox Support about this, but you do need to contact your ISP (Internet Service Provider) i.e. AT&T, COX, Cable One etc. So you can get your IP changed. There’s just no way of knowing who is running your IP address through any type of IP lookup service. It could be your bank, your real estate agent, or a tech-savvy teenager who’s also a hacker. However, one thing is clear It is possible to be traced by someone—a stalker, an investigator or even a.

If you use a different computer or device at work, or utilize a public network like a hotel or coffee shop, a different number is generated.

This number is called your IP address, which is short for Internet Protocol. This IP address indicates that your computer and ISP use an established set of rules to transmit data over networks using a unique number. It is similar to receiving a different address or phone number when you move to a new home.

IP Addresses Used to be Just Numbers

In the early days of the Internet, back in the 1970s, numbers instead of names were used to distinguish between the millions of users. Earlier IP numbers used a system called IPv4, which consisted of 32 bits, or four digits separated by periods, and 256 possible numerical combinations.

Today, with billions of online users, more ISPs have switched to a more secure format called IPv6, which provides 128 bits, 10 digits separated by periods, and 2,128 possible combinations for your digital footprint.

If you have several family members on the same network, they’ll all likely have the same IP address or slight variations.

How Can You (Or a Hacker) Figure Out Your IP Address

You can learn your IP number by typing “ipconfig” in the Windows command box or the Mac Utilities Terminal.

This number may occasionally change if you modify your router, modem or server, or you switch ISPs. Users familiar with their IP settings and security can create their own secure static address, or ask if their ISP allows them to purchase one.

Hackers sometimes create false IP addresses to cover their tracks and confuse authorities, or they use ones they’ve discovered by breaking into people’s systems.

Learning someone’s IP number usually requires breaking into their system, which can be defended against by a strong firewall, an encrypted router password, or a regularly locked phone. These defenses help keep people out, even if hackers find your IP number through other means, such as malware or one of your kids sharing it during an online conversation.

It’s generally difficult to learn someone’s personal identity from the IP number alone. The only exceptions seem to be poorly-secured ISPs, or law enforcement trying to narrow down suspects and online activity in a certain geographic area.

How Do You Protect Your IP Address

If you’re concerned about people finding your IP address, consider logging in through a VPN service (remote desktop), or logging into a proxy server, which can create new IP addresses. Using a public WiFi provides a different IP address, but greatly increases the risk of people spying on your activity.

We've encountered a wide range of questions and assumptions about what information you can find regarding an IP address. We decided to go ahead and create a detailed guide on the IP address information overview.

IP Address basics

At its core, an IP address is quite similar to a physical street address. It allows other devices to identify and connect to the device at the IP address. Perhaps without you realizing it, your web browser has connected to multiple IP addresses in order for you to read this post and you are using multiple IP addresses yourself.

Types of IP Addresses

IPv4 vs IPv6 Addresses

When most of us starting connecting to this amazing thing we call the Internet, we were all using IPv4 addresses. An IPv4 address looks something like and there are 4,294,967,296 (2^32) addresses in total. When originally deployed in 1983, it was assumed that 4.2 billion IP addresses would be more than sufficient for us to use. Turn the clock to 2020 and we've exhausted all 4.2 billion IPv4 addresses.

Starting in the late 1990s, the Internet Engineering Task Force (IETF) began addressing the impending IPv4 address exhaustion and created IPv6. While your typical IPv4 address looks like, an IPv6 address looks like 2001:0db8:0000:0000:0000:ff00:0042:8329. The biggest and most important difference is that IPv6 allows us to go from 4.2 billion addresses to 340,300,...,000 (2^128) addresses. In case you were wondering, that's called 340 Undecillion.

While IPv6 should allow for every single internet-connected device its own IP address for the foreseeable future, IPv6 and IPv4 are not compatible so the adoption has been slower than IETF and others had hoped for. We could do an entire post on that alone.

What Is My Ip Address Now

Dynamic vs Static IP Addresses

Because the transition to IPv6 has been slow, most of us are using dynamic IP addresses. This means that your phone, router, etc may have its IP address changed periodically. When this happens you don't even notice. Unless you're hosting a server this doesn't impact you. If you stumbled upon this because you are hosting a server and your dynamic IP address makes it hard for people to connect to you, check out a Dynamic DNS service such as noip.com

Some people (and typically businesses) have what's called a static IP address. While a dynamic IP address may change, a static IP address does not. The pros and cons of a dynamic vs static IP address are another topic we could make an entire post on.

Public vs Private IP Addresses

While most IP addresses are public, meaning that people from all over the world can connect to it (just like you connected to a number of IP addresses to read this post), there are some ranges that have been set aside for private use. The best example is if you have a router you connect your phone or computer to. The private IP ranges for IPv4 are: – – –

If you have a router, you can have and I can have the same address.

Full IP address information

The reason that our amazing customers use IPinfo is because of the incredible information you can learn about a single IP address. Using our basic service, I looked up my IP address as I was writing this at Starbucks (Trenta water with either a Grande Americano or Grande Caramel Machiatto in case you're wondering) and this is what our services at IPinfo provided:

The Basics - Geolocation

What If Someone Knows My Ip Address

Most of this information is straight forward, I want to make note that if you look up the latitude/longitude listed, you won't find a Starbucks on the map. Why is that? IP address geolocation is aimed at city or postal code level, not at the exact physical location.


With an ASN you can learn when it was allocated ownership of the IP, how many IPs they own, their main domain, business name, and what type of entity they are.

Hosting Data

Privacy API

This service allows you to learn whether or not the IP address in question is likely coming from a provider that is providing privacy services to the actual end user. IP address:

Abuse Contact API

Is this API address engaging in some type of abuse, such as hacking, hosting copyrighted material, etc? You can quickly find out who to contact to report this behavior.

Common Questions on IP Information

The most common questions we see around learning about an IP address are:

Q: How do I look up information on a specific IP address?
A: That's exactly what IPinfo is all about. Once you create an account, you can use our web-based tool in your account at https://ipinfo.io/account. Simply type in the IP address and we'll take care of the rest.

Q: How someone can use IP address information? What can someone do with your IP address?
A: We have amazing customers doing some incredible things with this information, from providing geo-specific content to security research to learning more about their customers and habits based on location.

What If Someone Knows My Ip Address Can They Find Me

Q: Can I track the physical location of my phone or an individual person based on their IP address?
A: In short, no, not really. You can get a general idea of where your phone is, but to track it down to the table it is sitting on is not really feasible. For those of you like myself who value privacy, this should come as a relief.
