What Can Someone Do With Your IP Address?
An IP address is less dangerous than many online videos claim, but it is not meaningless either. Here is what it can and cannot reveal.
By Siddharth ShankarUpdated October 18, 2026Your IP address shows your internet provider and a rough location, usually your city or region, not your street. On its own it cannot reveal your name or let someone into your devices. The real risks are targeted attacks on your router, online harassment and being identified by your provider through a legal request. Keep your router updated, change default passwords and treat threats that mention your IP as a scare tactic.
Scammers start with details that have already leaked. Is your email one of them?

Every device that connects to the internet uses an IP address. Websites, games and email servers see it as a normal part of how the internet works. That makes it one of the most widely shared pieces of data about you, and one that scammers like to use in threats.
What an IP address reveals
- Your internet provider, such as your broadband or mobile company.
- An approximate location, often the city or region where the provider routes your connection. It is frequently off by many miles.
- Whether the connection looks like home, mobile, business or a VPN.
It does not reveal your name, street address or what you are doing online. Only your internet provider can link an IP address to your account, and it normally only shares that with a legal request.
Is an IP address personal data?
In many places, yes. The UK regulator, the ICO, notes that the UK GDPR specifically includes online identifiers such as IP addresses in the definition of personal data, because they can single out a user.
Your best defence is knowing what scammers may already have. Check your email free.

What someone can actually do with it
- Estimate your area. Useful to a harasser only if combined with other details.
- Target your network. If your router has old software or a default password, an attacker may try to break in.
- Flood your connection. In gaming, people sometimes knock opponents offline with denial-of-service attacks.
- Link activity. Websites and advertisers can use it, with other signals, to recognise repeat visits.
- Make threats. Scammers send emails quoting your IP to scare you into paying. The IP proves nothing.
What they cannot do with it alone
They cannot find your exact home, read your messages, see your files or take over your phone using only your IP address. Claims like “I have your IP, I know where you live” are almost always bluffing. Doxxing usually relies on other details, such as usernames and photos. See what doxxing is.
How to protect yourself
1Update your router
Install firmware updates or ask your provider for a newer router.
2Change default passwords
Change the router admin password and the Wi-Fi password from the ones printed on the box.
3Keep devices updated
Most attacks use old, known flaws.
4Be careful with links
Clicking a link can reveal your IP to whoever runs the page. Avoid links from strangers.
5Consider a VPN where it helps
A VPN hides your IP from the sites you visit and is useful on public Wi-Fi or in gaming. It does not make you anonymous.
Your IP address changes
Most home internet connections get a dynamic IP address that can change over time, and mobile data addresses change often. An old IP address from a breach or a gaming session may no longer point to you at all.
Home routers are the real weak point
Many home routers stay on old software for years. Check your provider’s app or the router admin page for updates, and replace very old routers that no longer receive them.
IP addresses in data breaches
Breach records sometimes include login IP addresses. These are low risk on their own but can help attackers guess your location or time zone. See what each type of breached data means.

Frequently asked questions
Can someone find my house from my IP address?
Not your exact address. An IP usually points to a city or region. Only your provider can link it to your account.
Can someone hack me with my IP address?
Only if your router or devices have weaknesses, such as old software or default passwords. Keep them updated.
Is my IP address personal data?
In the UK and EU it can be. The ICO lists IP addresses as online identifiers.
Should I worry if a scammer quotes my IP?
No. It is a scare tactic. Do not reply or pay.
Does a VPN hide my IP?
It hides your IP from the sites you visit, but the VPN provider can see it.
