Ultimate Guide to Verifying IP Addresses in Linux Environments

October 22, 2024 by admin

An IP address (Internet Protocol address) is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. An IP address serves two main functions: host or network interface identification and location addressing.

There are two main types of IP addresses: IPv4 and IPv6. IPv4 addresses are 32-bit numbers, while IPv6 addresses are 128-bit numbers. IPv4 addresses are typically written in the form “a.b.c.d”, where a, b, c, and d are numbers between 0 and 255. IPv6 addresses are typically written in the form “a:b:c:d:e:f:g:h”, where a, b, c, d, e, f, g, and h are hexadecimal numbers.
