Understanding IP Addresses
Before diving into the practical steps of connecting to another computer via an IP address, it’s essential to familiarize ourselves with what an IP address is and its fundamental role in networking.
What is an IP Address?
An IP (Internet Protocol) address is a unique identifier for a device on a network. It allows one device to communicate with another by sending data packets back and forth. IP addresses come in two versions: IPv4 and IPv6.
-
IPv4: This is the most commonly used version, represented by a series of four numbers separated by periods (e.g., 192.168.1.1). Each number can range from 0 to 255.
-
IPv6: This newer version supports a far larger address space and is represented in hexadecimal format, primarily to cater to the growing number of devices connected to the internet.
Types of IP Addresses
IP addresses can be categorized into two main types:
-
Public IP Addresses: These are assigned by your Internet Service Provider (ISP) and are unique across the entire internet. They are used to identify a network externally.
-
Private IP Addresses: These are used within local networks. Devices connected to a router within the same network may have identical private IP addresses, as they don’t connect directly to the internet.
