Introduction to Internet Addresses

What are Internet Addresses?

Internet addresses are unique identifiers used to locate and communicate with devices on the internet. There are two main types of internet addresses:

IP Addresses

IP (Internet Protocol) addresses are numerical labels assigned to each device connected to a computer network that uses the Internet Protocol for communication.

IPv4 Addresses

IPv4 addresses are 32-bit numbers, typically written in dotted-decimal notation:

192.168.1.1

IPv6 Addresses

IPv6 addresses are 128-bit numbers, written in hexadecimal and separated by colons:

2001:0db8:85a3:0000:0000:8a2e:0370:7334
Note: IPv6 was developed to address the exhaustion of IPv4 addresses and provides a much larger address space.

Domain Names

Domain names are human-readable addresses that map to IP addresses through the Domain Name System (DNS).

Domain Name Structure

A domain name consists of several parts:

www.example.com
Note: Domain names make it easier for humans to remember and access websites, while computers use IP addresses for actual communication.

IP Addresses vs Domain Names

Feature IP Addresses Domain Names
Format Numerical (e.g., 192.168.1.1) Text-based (e.g., example.com)
Human Readability Difficult to remember Easy to remember
Purpose Network routing and communication Human-friendly identification
Resolution Direct network addressing Requires DNS resolution
