(also IPv4 address notation)
Dotted decimal notation is a human-readable representation of IP addresses in the IPv4 (Internet Protocol version 4) format. It is expressed as a series of four decimal numbers, each ranging from 0 to 255, separated by periods (dots). Each decimal number represents an 8-bit binary value (octet), and the entire IP address comprises 32 bits.
IPv6 notation: The IPv6 address format uses 128 bits and is expressed in hexadecimal notation, separated by colons. An example of an IPv6 address is 2001:0db8:85a3:0000:0000:8a2e:0370:7334.
Dotted decimal notation is essential for configuring network devices, such as routers and firewalls, and for troubleshooting network issues. It’s crucial to understand how to convert dotted decimal notation to binary and vice versa, as well as how to use subnet masks and calculate network addresses.
