Explore the internet's origins in ARPANET, its distributed, no-central-control network of independent operators, and how sharing information drives worldwide connectivity and new applications.
Explore how IP addresses and MAC addresses identify devices on local area networks and guide data through switches to wide area networks, with analogies to mailing addresses and package routing.
Explore how binary represents numbers with on and off bits, compare decimal and binary, and understand octets and their role in IPv4 addressing.
Explore how bits and bytes build storage from kilobytes to terabytes, and why understanding these units matters for designing data-heavy applications.
Learn to convert binary digits to decimal for IP addresses by summing powers of two from the right, using on/off bits and values like 128 and 64.
Compute IPv4 addresses using a 32-bit structure divided into four dot-separated octets, applying left-to-right and right-to-left calculations. Explore private versus public networks and an introduction to subnetting.
Master IPv4 address calculation by combining octets, including 192 and 168, to form valid addresses. Learn that each octet maxes out at 255, guiding correct address construction.
Explain what IP is and why devices need an internet protocol address to connect, and discuss IPv4 limits and the move to IPv6 as the internet of things expands.
Apply foundational concepts of IP addressing by comparing IPv4 and IPv6, recognize how devices and IoT connect to the internet, and explore subnet mask basics.
Explore IPv6, a 128-bit Internet protocol with eight 16-bit groups, hex notation, and zero compression; compare IPv4 subnet concepts and identify network and host portions.
A subnetwork or subnet is a logical subdivision of an IP network. Basic of Networking, OSI Model, Binary to Hex and Decimal conversion, TCP/IP, Ethernet Networks, IPV4 address, Privat IP address range, Ipv6 addressing, Transition, Mechanisms, how to subnet in, IPv4, how to subnet IPV6, CIDR or Classless Inter-Domain Routing provides the flexibility of borrowing bits of the Host part of the IP address and using them as Network in Network The benefits of subnetting an existing network vary with each deployment scenario. In the address allocation architecture of the Internet using CIDR and in large organizations, it is necessary to allocate address space efficiently. Subnetting may also enhance routing efficiency, or have advantages in network management when subnetworks are administratively controlled by different entities in a larger organization. Subnets may be arranged logically in a hierarchical architecture, partitioning an organization's network address space into a tree-like routing structure, or other structures such as meshes.An IP address is an address used in order to uniquely identify a device on an IP network. The address is made up of 32 binary bits, which can be divisible into a network portion and host portion with the help of a subnet mask
