🌐 What Is an IP Address?
An IP (Internet Protocol) address is a unique identifier assigned to every device connected to a network.
It helps devices communicate and transfer data.
📌 Types of IP Addresses
1. Private IP Address
Used inside home or office networks
Examples:
- 192.168.x.x
- 10.x.x.x
- 172.16.x.x–172.31.x.x
2. Public IP Address
Used on the internet, assigned by ISPs.
3. Static IP
Fixed IP → Does not change
4. Dynamic IP
Changes automatically → Most common
⚔ IPv4 vs IPv6 — Key Differences
| Feature | IPv4 | IPv6 |
|---|---|---|
| Address size | 32-bit | 128-bit |
| Example | 192.168.1.10 | 2401:4900:4603:0001::1010 |
| Address count | 4.3 billion | 340 undecillion |
| Speed | Slower | Faster with auto-configuration |
| Security | Basic | Built-in IPsec |
| Format | Numeric, dot-separated | Hexadecimal, colon-separated |
