Learn about IP addresses, online privacy, and network security
Ever wondered how multiple applications on your computer can use the internet simultaneously with just one IP address? Dive into the world of network ports, well-known ports like 80, 443, and 22, and the fundamental differences between TCP and UDP ports.
Learn how legacy Class A, B, C, D, and E IP address ranges worked, reserved address blocks, and why classless routing (CIDR) replaced classful networks.
Dive deep into what a subnet is, how it divides large networks, and how it boosts efficiency, security, and management. Explore subnet masks, CIDR notation, and practical applications.
Discover how Dynamic Host Configuration Protocol (DHCP) automatically assigns IP addresses, subnet masks, default gateways, and DNS servers to your devices, and delve into its core DORA process.
Dive into the TCP/IP model to understand the layered architecture and protocols that enable data to travel across the internet, from your application to its destination and back.
Explore the fundamental differences between public and private IP addresses, how they function within your network, and the crucial role of Network Address Translation (NAT) in bridging the gap.
Dive into how Network Address Translation (NAT) allows multiple devices to share a single public IP address and its critical role in solving the IPv4 address shortage.
Understand the key differences between dynamic and static IP addresses and when to use each type.
A comprehensive guide to understanding the differences between IPv4 and IPv6 addressing, their structures, and why IPv6 is the future of the internet.
