There are several types of IP addresses, each serving different purposes and having specific characteristics. Understanding these types is key to effectively managing and troubleshooting network issues.

IPv4 vs. IPv6

IPv4

IPv4 (Internet Protocol version 4) is the most widely used IP address format. It consists of four sets of numbers ranging from 0 to 255, separated by periods (e.g., 192.168.0.1). This format provides around 4.3 billion unique addresses.

IPv6

IPv6 (Internet Protocol version 6) addresses the limitations of IPv4 by using a 128-bit address format, which allows for a virtually limitless number of unique IP addresses. IP Lookup: What Is My IP and How to Find It An IPv6 address is represented as eight groups of four hexadecimal digits separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).

The transition to IPv6 is ongoing, and many modern networks support both IPv4 and IPv6 to ensure compatibility and future-proofing.

Public vs. Private IP Addresses

Public IP Addresses

A public IP address is assigned to your device by your Internet Service Provider (ISP) and is used to identify your device on the internet. This address is globally unique and allows your device to communicate with other devices on the web.
