Explore how IPv4 enables unique identification of internet-connected devices using logical addressing, mirroring real-world address hierarchies, to support reliable data exchange between source and destination across networks.
IPv4 : Bits and Range7:14
Explain how IPv4 uses a 32-bit address divided into four eight-bit octets, dot-separated, with each octet ranging from 0 to 255, representing binary to decimal conversions.
Classification of IPv42:20
Class A : Theoretical3:46
Explore class A addressing in IPv4, where 8 network bits and 24 host bits yield 2^24 possible hosts per network, about 16.7 million.
Class B : Theoretical2:26
Class C : Theoretical2:48
Important Note1:21
Identify the network part and host part in IPv4, note that addresses with all zeros or all ones are not allocated to devices, and preview the three classes.
Why Theoretical Class A,B,C not possible to Implement Practically4:48
Practical Ranges for Class A, B, C, D and E6:44
Identify the ip class from the first octet ranges (class a to e) and determine the network and host parts accordingly, using 167.x.x.x as a class b example.
Class A : Practical8:12
Class B : Practical5:53
Class D : Practical4:54
Explain Class D addresses, ranging from 224 to 239, which are allocated for multicast with no host part, and how to identify multicast addresses in IP networks.
Class E : Practical2:57
Classification Conclusion : A, B, C, D and E2:48
Total IP Addresses Possible in IPv43:44
Extracting Network Id and Host Id from IP address.7:33
Broadcast IP address for Network6:33

Why Subnetting required?6:38
Subnetting Introduction : Definition1:26
Number of bits required for Subnetting.8:28
Subnetwork Creation Example 1 : Selecting subnetwork bits from host part.7:35
Subnetwork Creation Example 1 : Subnet Range and number of hosts per subnet.4:18
Analyze subnet ranges and determine usable hosts per subnet in a class 1 network, revealing four 64-address subnets with 62 usable hosts each.
Subnetwork Creation Example 1 : Finding Subnetwork ID for each Subnetwork.3:29
Explore how to identify subnets by separating the network portion and host portion of an IP address, determine the subnetwork IDs, and derive subnetwork ranges through example calculations.
Subnetwork Creation Example 2 : Different subnet bit position from example 116:19
Why Subnetmask required?5:49
Subnetmask Introduction : Definition2:40
Subnetmask Example 13:31
Subnetmask Example 28:32
Analyze how a class C network uses 255.255.255.224 to borrow three host bits, creating eight subnets and up to 30 usable hosts per subnet.
Subnetmask Example 34:51
Question : Finding subnetmask7:08
Default representation of Subnetmask along with IP Address.8:10
Extracting SubNetwork Id and Host Id from IP address by using Subnetmask.11:00
Identify the destination subnet and host within a class c network by applying a subnet mask, extracting the subnet id, and deriving the host id from the address.
How to create Subnetwork Broadcast IP Address.10:44
Question : On Subnetmask9:57
Why Variable Length Subnetmask (VLSM) required?12:11
Creating Variable Length Subnetmask (VLSM).16:38

Extracting SubNetwork Id by using VLSM11:19
Extract subnetwork ids by applying variable length subnet masks to destination IPs, illustrating how main network, subnetwork, and sub-subnet ranges are identified in IPv4.
Further depth on VLSM.6:58

TCP Characterstics : 113:58
Explore tcp characteristics: it provides a reliable byte stream with per-byte sequence numbers, port-based service points, and cumulative acknowledgments, enabling full duplex flow control via sliding window.
