Introduction

In the realm of internet networking, IP addresses serve as unique identifiers for devices connected to the internet. These addresses are crucial for routing data and ensuring proper communication between devices. However, not all IP addresses are valid or functional. One such example is the IP address 264.68.111.161, which, at first glance, appears to be a standard IPv4 address. Upon closer inspection, it becomes evident that this address is invalid due to the presence of an octet exceeding the permissible range.

What Is an IP Address?

An Internet Protocol (IP) address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. It serves two main functions: identifying the host or network interface and providing the location of the host in the network. IP addresses are categorized into two versions:

• IPv4 (Internet Protocol version 4): This is the most widely used version, consisting of four octets (8-bit numbers) separated by periods (e.g., 192.168.0.1). Each octet can have a value between 0 and 255, making the total range from 0.0.0.0 to 255.255.255.255.
• IPv6 (Internet Protocol version 6): Introduced to address the limitations of IPv4, IPv6 uses 128-bit addresses and is represented in hexadecimal format.

Decoding 264.68.111.161

Structure of the Address

The address 264.68.111.161 follows the IPv4 format, comprising four octets. However, the first octet, 264, exceeds the maximum allowable value of 255. This makes the address invalid within the IPv4 addressing scheme.

Valid Range of IPv4 Addresses

IPv4 addresses are structured as follows:

• First Octet: 0–255
• Second Octet: 0–255
• Third Octet: 0–255
• Fourth Octet: 0–255

Therefore, any address with an octet value greater than 255 is considered invalid. In this case, the octet value of 264 renders the entire address non-functional.
