IP stands for Internet Protocol. It is a set of rules that governs the format of data packets sent over a network.

• IP is responsible for addressing and routing packets across the internet.

• There are two versions of IP: IPv4 and IPv6.

• IPv4 uses 32-bit addresses and supports approximately 4.3 billion unique addresses.

• IPv6 uses 128-bit addresses and supports an enormous number of unique addresses.

• IPv6 was introduced to address the depletion of IPv4 addresses.

The port number used by DHCP is 67 (server) and 68 (client).

• Port 67 is used by DHCP server to listen for client requests

• Port 68 is used by DHCP client to send requests to the server

• DHCP uses UDP protocol for communication

DHCP assigns IP addresses, DNS translates domain names to IP addresses, VLAN separates network traffic, IPv4 has 32-bit addresses, IPv6 has 128-bit addresses.

• DHCP (Dynamic Host Configuration Protocol) assigns IP addresses to devices on a network dynamically.

• DNS (Domain Name System) translates domain names to IP addresses.

• VLAN (Virtual Local Area Network) separates network traffic into different segments.

• IPv4 has 32-bit addresses, allowing for approximately 4.3 billion unique ...read more

ISIS and MDLS are protocols used in networking for routing and network management.

• ISIS (Intermediate System to Intermediate System) is a routing protocol used to exchange routing information between network devices.

• MDLS (Management Data Input/Output Link Service) is a protocol used for network management tasks such as monitoring and configuration.

• ISIS is commonly used in large enterprise networks and internet service provider networks.

• MDLS helps network administrators to mana...read more

Networking is the practice of connecting computers and other devices to share resources and information.

• Networking involves the use of hardware such as routers, switches, and cables to create a network.

• It also includes the use of software protocols like TCP/IP to facilitate communication between devices.

• Networking allows devices to share resources such as files, printers, and internet connections.

• Examples of networking technologies include Ethernet, Wi-Fi, and VPNs.

OSI Layers are a model for network communication. There are 7 layers, each with a specific function.

• Layer 1 - Physical layer: Transmits raw data bits over a physical medium

• Layer 2 - Data link layer: Provides error-free transfer of data frames between nodes

• Layer 3 - Network layer: Routes data packets between networks

• Layer 4 - Transport layer: Provides reliable end-to-end data delivery and error recovery

• Layer 5 - Session layer: Establishes, manages and terminates sessions betwe...read more
