Understanding IP Addresses: A Brief Primer
Before diving into the nitty-gritty of finding your Cisco router’s IP address, it’s essential to grasp the basics of IP addresses. An IP address, or Internet Protocol address, is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol to communicate. IP addresses serve two primary functions: they identify the host or network interface and provide the location of the host in the network, enabling data to be routed across the internet.
Types of IP Addresses
There are two main types of IP addresses: IPv4 (Internet Protocol version 4) and IPv6 (Internet Protocol version 6). IPv4 addresses are 32-bit numbers, typically expressed in dotted decimal notation (e.g., 192.168.1.1), while IPv6 addresses are 128-bit numbers, usually represented in hexadecimal notation (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334). For most home networks and Cisco routers, IPv4 addresses are the norm.
