Summary of Free CCNA | IPv4 Addressing (Part 1) | Day 7 | CCNA 200-301 Complete Course

00:00:00 - 00:40:00

The video explains how IPv4 addresses are assigned and how they are divided into network and host portions. It also covers how to convert between binary and dotted decimal, and how to find a specific address. The video provides tips on how to pay for CCNA training and how to leave a tip for the author.

• 00:00:00 This video explains how IP addresses are assigned at the network layer of the OSI model, and how routers work at this layer.
• 00:05:00 In this video, the instructor explains how an IPv4 address is composed of groups of 8-bit numbers and how binary and dotted decimal are used to write them. He also explains how hexadecimal is used.
• 00:10:00 In this video, the instructor teaches how to convert between decimal and binary, and explains the term "octet." He also provides an example of how binary can be converted to decimal.
• 00:15:00 In this video, the author explains how to convert decimal numbers to binary. He covers examples of converting 127 to binary, 207 to binary, and 31 to binary.
• 00:20:00 An IPv4 address is a series of 32 bits, and is split up into 4 octets. The first 24 bits represent the network portion of the address, and the last 8 bits represent the host portion. The first octet is the network portion, and the last three octets are the host portion for addresses in the class A range, the first octet is the network portion, and the last two octets are the host portion for addresses in the class B range, the first octet is the network portion, and the last octet is the host portion for addresses in the class C range, and the first octet is the network portion, and the last octet is the host portion for addresses in the class D range.
• 00:25:00 This video explains the IPv4 addressing system, which uses classes A, B, and C. The first octet is divided into 240-255 ranges, and class E is for experimental uses. The leading bits of the first octet indicate the network portion of the address while the size of the rest bit field indicates the number of hosts in the address.
• 00:30:00 In this video, the instructor covers IPv4 addressing basics, including the use of slash notation and dotted decimal netmask notation, network and broadcast addresses, and the use of these addresses to send packets to all hosts on a local network.
• 00:35:00 This video covers the basics of IPv4 addressing, including converting between binary and dotted decimal. There are 10 questions in the quiz, and after answering them, the student is given a summary of what he or she has learned. Supplementary materials including flashcards and a packet tracer lab will be available after the quiz.
• 00:40:00 In this video, the author walks viewers through the basics of IPv4 addressing, including how addresses are divided up among networks and how to find a specific address. The video also provides tips on how to pay for CCNA training and how to leave a tip for the author.
