What is an IP Address?
What is IPv4?
IPv4 (Internet Protocol version 4) is the most widely used IP standard. It consists of four groups of numbers separated by dots, e.g. 192.168.1.1. It supports approximately 4.3 billion unique addresses.
What is IPv6?
IPv6 (Internet Protocol version 6) is the next-generation IP standard designed to replace IPv4. It supports an enormous address space (3.4×10³⁸ addresses), e.g. 2001:4860:4860::8888.
Public vs Private IP
A Public IP is visible on the internet and assigned by your ISP. A Private IP (e.g. 192.168.x.x, 10.x.x.x) is used within your local network (LAN) and is not directly reachable from the internet.
Why Does IP Matter?
An IP address is the unique identifier for every device on a network. Web hosting servers need a public IP so that users worldwide can reach your website. It is also used for geolocation and access control.
