Question 1

What is my IP address?

Accepted Answer

Open howtofindtheip.com and your public IP address is shown instantly at the top of the page, along with your ISP and approximate location. It is the address your ISP assigns to your connection and the one every website sees.

Question 2

What is the difference between a public and a private IP address?

Accepted Answer

A private IP (like 192.168.1.42) identifies a device inside your own network and is not reachable from the internet. A public IP identifies your whole network to the internet and is assigned by your ISP. Websites only ever see the public one.

Question 3

What is the difference between IPv4 and IPv6?

Accepted Answer

IPv4 addresses (203.0.113.42) are 32-bit numbers with about 4.3 billion combinations, and the world has run out. IPv6 addresses (2606:4700::1111) are 128-bit with a practically unlimited space. Modern networks run both side by side.

Question 4

Does my IP address show my exact home address?

Accepted Answer

No. An IP address can usually be traced to a city or region and to your internet provider, but not to your street or house. Only your ISP can link an IP to a specific customer, and only for legal reasons.

Question 5

Why does my IP location show the wrong city?

Accepted Answer

IP geolocation is based on databases mapping address ranges to places, and the reported city is often where your ISP's routing equipment sits rather than where you are. City-level accuracy is typical; street-level accuracy is impossible from an IP alone.

Question 6

Can two devices have the same IP address?

Accepted Answer

On the public internet, no — addresses must be unique. Inside a private network many devices share one public IP through NAT while each holds its own private address like 192.168.1.x. That is why a whole household appears online under a single public IP.

Question 7

How often does my IP address change?

Accepted Answer

Most home connections use dynamic IPs that change whenever the router reconnects or its DHCP lease expires — often every few hours or days. Business lines and paid static-IP services keep the same address indefinitely.

Question 8

Can I hide or change my IP address?

Accepted Answer

Yes. A VPN, proxy or the Tor network replaces the address websites see; rebooting a router with a dynamic IP may also hand you a new one. Traffic from these services is often detectable — verify any address with the Proxy & VPN Check tool.

Question 9

What is my router's IP address?

Accepted Answer

Your router has two: a private gateway address (commonly 192.168.1.1 or 192.168.0.1) used to open its settings page, and the public WAN IP it uses on the internet. The gateway can be found with 'ipconfig' on Windows or in your phone's Wi-Fi details.

Question 10

Is my IP address blacklisted?

Accepted Answer

Check instantly with the free IP Blacklist Check tool: it queries major spam and abuse DNSBLs live from your browser and reports every hit, plus how to request removal.

Question 11

Why does my IP show up as a proxy or VPN?

Accepted Answer

Detection databases flag addresses that relay traffic — VPN servers, Tor exits, hosting providers, or occasionally misconfigured home routers. If your ordinary home IP is wrongly flagged, it usually clears as the databases update.

Question 12

Do you store my IP address?

Accepted Answer

No. The site is fully static with no backend, and it sets no cookies of its own. Lookups are performed by your browser against independent public APIs under their own privacy policies.
