IPv4
Your public IPv4 addressIPv6
Your public IPv6 addressWhat Do These Mean?
IPv4
32-bit address written as four numbers separated by dots (e.g., 203.0.113.45). The most common format, used by virtually every internet-connected device.
IPv6
128-bit address written in hexadecimal (e.g., 2001:db8::1). The next-generation protocol with virtually unlimited addresses, increasingly assigned alongside IPv4.

Frequently Asked Questions
What is the technical difference between IPv4 and IPv6?
They differ in address format length and the global availability pool.
Why does the location show a different city than where I actually am?
Geo-IP databases map to your ISP's routing hub, not GPS coordinates.
Can this tool detect if I am using a VPN or Proxy server?
It will display the exit IP of the VPN, effectively masking your real IP.
Does this tool expose my exact physical street address?
No, only regional IP registry data is visible publicly.
Why does my IP address change periodically?
Most ISPs use dynamic IP assignment based on router lease renewals.
Detailed Guide & Overview
What Is My IP Address? Understanding Your Network Identity
An IP (Internet Protocol) address is a unique numerical label assigned to every device connected to a network. It serves two primary functions: identifying the host or network interface, and providing the location of that device in the network. When you access any website, your IP address is visible to the server hosting that site — it is the return address for all internet traffic to and from your device. Our What Is My IP tool displays your current public IP address along with geographic and ISP information instantly.
Public IP vs Private IP: What's the Difference?
- Public IP Address: The IP address assigned to your internet connection by your ISP (Internet Service Provider like Jio, Airtel, BSNL, or ACT). This is the address visible to the outside world — to websites, servers, and online services you connect to. All devices on your home or office Wi-Fi network share a single public IP.
- Private IP Address: The address assigned to your individual device (phone, laptop, smart TV) within your local network by your Wi-Fi router. Private IP ranges are 192.168.x.x, 10.x.x.x, and 172.16–31.x.x. Private IPs are invisible to the internet and are only meaningful within your local network.
- NAT (Network Address Translation): The router mechanism that maps many private IP addresses to a single public IP. This is why all your home devices appear to the internet as having the same IP address.
IPv4 vs IPv6: The Two IP Standards
IPv4 is the original IP standard — a 32-bit number written as four groups of 0–255 separated by dots (e.g., 203.197.32.88). IPv4 supports approximately 4.3 billion unique addresses — a number that has been exhausted as internet usage has grown.IPv6 is the modern standard — a 128-bit address written as eight groups of hexadecimal digits (e.g., 2401:4900:1f3e:b9f5::1). IPv6 supports 340 undecillion addresses — effectively unlimited. Most modern ISPs in India now assign both IPv4 and IPv6 addresses.
What Your IP Address Reveals About You
Your public IP address can reveal:
- ISP name: The company providing your internet (Jio, Airtel, BSNL, etc.)
- Approximate location: Country, state/region, and city — but not your precise address. IP geolocation is accurate to city level (usually within 50km) but not to street or building level.
- Connection type: Residential, commercial, or mobile data connection
- ASN (Autonomous System Number): The technical identifier for your ISP's network
Your IP does not reveal your name, phone number, exact home address, or any personal information without a court order to the ISP.
Why Your IP Address Changes (Dynamic vs Static IP)
Most home internet connections use dynamic IP addresses — assigned by the ISP's DHCP server and potentially changed each time you reconnect or every few days.Static IP addresses are fixed and never change — used by businesses hosting servers, VPNs, and services that need a consistent address. For home users, Jio, Airtel, and BSNL all use dynamic IPs by default. A static IP is available as a paid add-on from most Indian ISPs.
