Every single device connected to the internet—whether it is your smartphone, desktop workstation, smart TV, or home Wi-Fi router—requires a unique numerical identifier to transmit and receive data packets across the global web. That identifier is called an Internet Protocol (IP) address.
1. The Post Office Analogy: How an IP Address Functions
Think of the internet as an ultra-fast global postal service. When you write a physical letter to a friend, you write their delivery address on the envelope, and you also write your return address on the back so they know where to reply.
In digital networking, an IP address acts as both the shipping destination and the return address. When you type myiptools.net into your browser:
- Your device sends a data packet containing your Public IP to our edge server.
- Our server inspects your IP address to know where on the planet to send the website's HTML, CSS, and imagery.
- The requested packets travel across fiber-optic cables and cell towers until they arrive precisely back at your device.

There are two primary generations of IP addresses in active deployment across the globe today:
| Feature | IPv4 (Internet Protocol v4) | IPv6 (Internet Protocol v6) |
|---|---|---|
| Format | 32-bit numerical (e.g., 106.222.213.79) |
128-bit hexadecimal (e.g., 2401:4900:1c1a::1) |
| Total Pool | ~4.29 Billion addresses (Exhausted) | ~340 Undecillion (Virtually Infinite) |
| Routing Efficiency | Requires NAT (Network Address Translation) | Direct peer-to-peer end-to-end routing |
| Security (IPsec) | Optional add-on | Architecturally integrated |
3. Public vs. Private IP Addresses
Your home or office network utilizes two distinct types of addresses:
- Private IP (Local LAN): Assigned by your local router via DHCP (typically starts with
192.168.x.xor10.x.x.x). It allows your printer, laptop, and phone to talk to each other without exposing them to the raw public internet. - Public IP (WAN): Assigned to your router by your Internet Service Provider (like Bharti Airtel, Jio, Comcast, or Verizon). This is the single address that outside websites see when you browse.
4. Does an IP Address Reveal Your Exact Home Address?
No. A common myth is that an IP address pinpointing your street name and house number. In reality, commercial IP geolocation databases (like MaxMind, IPinfo, and IP-API) map your IP to your ISP’s local distribution routing node, central exchange office, or general municipality/city level (typically accurate within 2 to 10 kilometers).

Using an encrypted VPN hides your actual public IP behind an encrypted tunnel, allowing you to browse privately with zero logging.
