Key Concepts

IP Addresses

IP addresses are numerical labels assigned to devices on a network. They are used to identify and locate devices and enable communication between them. In the context of IPv4, these addresses are 32-bit numbers typically represented in dotted-decimal notation.

Dotted-Decimal Notation

Dotted-decimal notation is a human-readable representation of a 32-bit IP address. It separates the address into four groups (octets) of decimal numbers, each ranging from 0 to 255, divided by dots, making it easier to interpret and administer.

Binary Notation

Binary notation is a numeral system that represents values using two symbols: 0 and 1. When expressing IP addresses, the binary form converts each decimal octet into its equivalent 8-bit binary sequence, providing a clear view of the underlying bit-level structure.

Decimal to Binary Conversion

Decimal to binary conversion is the process of translating a base-10 number into its equivalent base-2 (binary) form. In the context of IP addresses, each decimal octet is converted into an 8-bit binary number, often including leading zeros to ensure a consistent 8-bit format.

8-bit Octets

An 8-bit octet is a segment of the 32-bit IP address that constitutes one of the four parts in dotted-decimal notation. Each octet represents a byte and, when converted to binary, always appears as an 8-digit binary number, providing a structured subdivision of the address.

0:00 Hello.

00:01 The question here is simply to encode each of the following bit patterns using the decimal dotted notation.

00:09 So the dotted decimal notation simply we know that each 8 bits in a row are used to represent a single number that can range from 0 to 255 and then we have a dot and then a second number represented by this next 8 bits and so on.

00:29 So let's start by this example, example a.

00:34 So the first eight bits are the following.

00:37 So one, two, three, four, five, six, seven, eight.

00:41 So these are the first eight bit patterns.

00:45 And then also we have one, two, three, four, five, six, seven, eight.

00:49 This is the second eight bit patterns.

00:52 And finally, we have these, which are the last eight bit patterns.

00:57 So now we need that three numbers and separated by a dot in between.

01:03 So this first one here, we can see it's one, zero, one, and the rest are zeros.

01:11 So in that case, we know that this is a one plus four.

01:16 So the first one is five.

01:18 So we have five dot.
