Full Details of IP Address



Here’s the full concept of IP addresses:

🔸 1. Local / Private IP

•These are automatically generated by your router.

•Each device like phone, PC, or laptop gets a different local IP.

•Example: 192.168.1.1, 192.168.1.2, etc.

•These IPs only work within your home or office network.

---

🔸 2. Public IP

•This is assigned by your ISP (Internet Service Provider).

•It’s the IP your router uses to connect to the internet.

•The whole world sees this public IP when you go online.

🔸 3. Static vs Dynamic IP

Static IP:

•Never changes.

•Used for things like servers, CCTV, or any important device.

Dynamic IP:

•Changes from time to time.

•Commonly used for normal devices like phones and laptops.

•Older format, like 192.168.5.18

•Has around 4.3 billion unique addresses.

•Due to shortage, many addresses are reused or masked.
