What Is an IP Address?
IP Address means Internet Protocol address is an numerical unique identifier assigned to every device connected to a network.

Two Main Versions: IPv4 and IPv6
IP addresses are the foundation of modern internet based communication. IPv4 (32-bit) used currently in web but is exhausted, while IPv6 (128-bit) is the future with built-in security and auto-configuration. Modern networking relies on CIDR for flexible allocation, subnetting for security and performance, and NAT to stretch limited IPv4 space. Whether you're building a blog or ecommerce website, configuring a server, or just troubleshooting Wi-Fi, IPs essential now a days.
IPv4 (Internet Protocol Version 4) Address
- A 32-bit address written as a set of 4 numbers (octets) between 0–255 and each numbers separated by the dots like 192.168.1.99
- Each octet of IPv4 represents 8 bits, so the size of complete address is 32 bits
- Maximum no of IPv4 persists ~4.3 billion distinct IP addresses. It is not enough for modern day requirement for devices, that was the main reason to develop the IPv6.
IPv6 or Internet Protocol Version 6) Address
- A 128-bit address written as set of eight four hexadecimal characters, separated by colons: 2001:0db8:85a3::8a2e:0370:7334
- Leading zeros can be omitted, and a double colon (::) can replace a sequence of all-zero groups (once per address)
- Provides huge unique addresses to resolve lack of unique IP for each and every devices even IoT devicesfvh1a2b3c4 to have its own IP
