While not a necessity, it is a good idea to obtain a new IP address. Note the current IP address assigned to you from your internet service provider (ISP). You may be able to obtain a different IP address by performing a DHCP release and renew from your router's WAN connection page. A few ISPs give you the same. Everyone on the Internet has to have an IP address to send emails, look up information or buy online. It's as simple as this: When you're connected, you have an actively working IP address. And depending on where you are, your IP address can change. A lot of Internet chatter that says our IP addresses can reveal our identities is not accurate. Either alter the IP address or select Obtain an IP address automatically to have the router control the IP address. If you leave the setting to obtain an IP address automatically, the router automatically assigns an IP address to the computer. However, when you enter the IP address information, the computer's IP address stays static. 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.
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 216.239.32.21 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 216.239.32.21, 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.
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:
10.0.0.0 – 10.255.255.255
172.16.0.0 – 172.31.255.255
192.168.0.0 – 192.168.255.255
If you have a router, you can have 192.168.1.1 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
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.

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.
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.
If you have more questions regarding IP address information, we'd love to hear there. We are constantly learning and developing incredible tools to help our customers makes the most of the Internet and the data out there. We'd love to see what ideas you have.
Every device that connects to the internet has an IP (Internet Protocol) address.
They're needed for devices talk to each other and exchange data.
Your IP address may look like
- 50.201.69.200 – for IPv4
or - 2001:4860:4000:4uh5:b2fw:0000:8e5d:6432 – for IPv6
– depending on how modern your equipment is.

What Happens If Someone Has My Ip Address Number
But what are the dangers of someone knowing your IP address – and should you hide it?
Denial of Service attack
If someone knew you IP address – they could perform a Denial of Service attack on your router.
This will flood your connection so that your internet stops working – or at best just slows down to a crawl.
This also affects your ISP (Internet Service Provider) – so fortunately most will have systems to detect and manage Denial of Service attacks in their network.
However, these attacks require resources and run the risk of the attacker getting caught and in trouble with their ISP and the law – so fortunately they're not often directed at home internet connections.
Discover your location
There are online databases which show the geographic location of IP addresses.
Someone with your IP address could uses these to discover your location.
In most cases, these only show your city and state – but this information could be enough to narrow down your identity – such as the school you go to.
Report your IP address as 'bad' to websites and services
Some websites, like AbuseIPDB, list 'bad' ip addresses – which have been used for hacking, spam and other abusive activity on the Internet.
Someone with you IP address could report it as 'bad' – even without you doing anything wrong.
What Happens If Someone Has My Ip Address Search
Do this enough times and you'll have troubles accessing websites which block 'bad' IP addresses.
Report your IP address to law enforcement
Taking things a step further – someone with your IP address could also report it as 'bad' to law enforcement.
This is unlikely to be taken seriously without evidence – but it still may attract unwanted attention.
Can I be hacked using my IP address?
No – at least least it's extremely unlikely.
For this to happen you would have to have an existing vulnerability – such as an unsecured router with a default password or open ports.
Fortunately this is extremely rare. Modern routers are designed with security in mind – for example making you set a password before it can be used. And ISP's often use a firewall to help protect your connection.

Is It Bad If Someone Has My Ip Address
The best way to do this is using a VPN – such as Private Internet Access.
Private Internet Access is a highly trusted VPN service which:
- hides your IP address
- gives you access via 46 countries – further hiding your location
- is the only proven no-log VPN service in the world!
I've used Private Internet Access for several years and highly recommend them – they offer extreme value for money with prices from $4.42/month.
