What Is My IP Address? Complete Guide (2026)

An IP address (Internet Protocol address) is a unique numerical label assigned to every device connected to a network. It serves two functions: identifying the device and indicating its location in the network.

IPv4

The most common format: four numbers (0–255) separated by dots. Example: 192.168.1.1 or 203.88.142.5. IPv4 supports about 4.3 billion unique addresses — a number that has been exhausted globally, leading to the transition to IPv6.

IPv6

The newer format: eight groups of four hexadecimal digits separated by colons. Example: 2401:4900:1c5c:a6c1::1. IPv6 supports 340 undecillion addresses — effectively unlimited. India's major ISPs (Jio, Airtel, BSNL) now assign IPv6 addresses by default on mobile networks, though IPv4 is still dominant for broadband.

How they differ in practice:

• IPv4 addresses are easier to read and remember.
• IPv6 has built-in security features (IPsec is mandatory).
• Most websites and servers still operate on IPv4 — dual-stack (both) is common.
• Your device may show an IPv6 address to some sites and IPv4 to others.

You have two types of IP addresses simultaneously, and confusing them is the most common IP address mistake:

Private IP Address

Assigned by your router within your home or office network. Typical ranges:

• 192.168.x.x — most home routers
• 10.x.x.x — larger networks, ISPs
• 172.16.x.x to 172.31.x.x — medium-sized networks

Your phone, laptop, and smart TV each have different private IPs but share the same public IP. The internet cannot see your private IP.

Public IP Address

Assigned by your ISP (Jio, Airtel, BSNL, ACT, etc.) and visible to every website and server you connect to. When you search "what is my ip," you see your public IP. This is the address that can be geolocated, logged, and analyzed.

Key point: Changing your private IP (e.g., reconnecting to Wi-Fi) does NOT change your public IP. To change your public IP, you need to either reset your modem/router (for dynamic IPs) or use a VPN/proxy.

The simplest way: visit any "what is my ip" website and your public IP is displayed instantly. For private/local IP, use these device-specific methods:

Windows

• Open Command Prompt → type ipconfig → look for "IPv4 Address" under your active adapter.
• Or: Settings → Network & Internet → Wi-Fi/Ethernet → Properties.

Mac

• System Settings → Network → select your connection → shows IP address.
• Terminal: type ifconfig | grep inet

Android

• Settings → Wi-Fi → tap the connected network → scroll to see IP address.
• Or: Settings → About Phone → Status → IP Address.

iPhone / iOS

• Settings → Wi-Fi → tap the (i) icon next to your network → shows IPv4 and IPv6 addresses.

Linux

• Terminal: ip addr show or hostname -I

Your IP address exposes more than most people realize — but less than some fear.

What it CAN reveal:

• Country and city (approximate): Geolocation databases like MaxMind or IP2Location can identify your city with 60–80% accuracy in India. The accuracy is higher in metros, lower in smaller towns.
• ISP (Internet Service Provider): Whether you're on Jio, Airtel, BSNL, ACT Fibernet, etc. is immediately visible.
• Connection type: Residential, mobile data, business, VPN, datacenter.
• Timezone: Inferred from geolocation data.

What it CANNOT reveal:

• Your exact home address: IP geolocation points to ISP infrastructure, not your building or apartment.
• Your name: IP addresses are not linked to personal identity in public databases. Only your ISP (and law enforcement with a court order) can map an IP to a subscriber name.
• Other devices on your network: Websites only see your public IP, not your private network.

Dynamic IP: Changes periodically — assigned fresh by your ISP each time you reconnect. Most Indian residential connections (Jio, Airtel FTTH) use dynamic IPs. You can often get a new public IP by unplugging your router for 15–30 minutes, though ISPs with smaller IP pools may reassign the same address.

Static IP: Fixed and permanent — always the same. Required for hosting servers, remote desktop access, or certain banking/enterprise systems. ISPs in India charge ₹200–₹500/month extra for a dedicated static IP.

VPN (Virtual Private Network): Routes your traffic through a server in another location. Websites see the VPN server's IP, not yours. Effective VPNs also encrypt traffic between you and the VPN server.

Under India's IT Act and DPDP Act 2023: Your IP address is considered personal data when combined with other identifiers. ISPs are obligated to retain connection logs for 1 year under the IT (Intermediary Guidelines) Rules 2021. Law enforcement can request subscriber data mapped to an IP without a court order in cases involving national security, under Section 69 of the IT Act. Using a VPN for legal activities is not prohibited in India.
