IPv4 address
An IPv4 address is a numerical label used to identify a device on a computer network that uses Internet Protocol version 4 for communication.
Also known as: Internet Protocol version 4 address
How big is it?
4 B of data
Binary address size · standard
A little perspective
About 4 times the data of ASCII character.
ASCII character: An ASCII character is a letter, digit, punctuation mark or control code encoded using the American Standard Code for Information Interchange.
Measurements, assumptions & sources +
IPv4 address
An IPv4 address contains exactly 32 bits, or four bytes. Text forms such as 192.0.2.1 occupy more storage because they encode punctuation and digits.
The marked binary address size is calibrated. Unmeasured illustration details are representative.
ASCII character
One ASCII character stored as one byte. UTF-8 characters can occupy more than one byte.

Why this measurement?
Why we use 4 B
For comparison, this page uses binary address size. The record labels this value standard, so the stated convention rather than an inferred average controls the comparison.
