Internet Protocol (IP) is a set of rules governing the format of data sent over the internet or local network, ensuring data packets are addressed and routed to their intended destinations. It is a fundamental component of the Internet Protocol Suite, which is essential for inter-network communications and is used in conjunction with other protocols like TCP and UDP to facilitate reliable data transmission.
Concept
IPv4, or Internet Protocol version 4, is a foundational technology that enables devices to communicate over the internet by assigning unique addresses to each device. Despite its widespread use, IPv4's 32-bit address space is limited to approximately 4.3 billion addresses, leading to the development of IPv6 to accommodate the growing number of internet-connected devices.
Concept
IPv6, or Internet Protocol version 6, is the most recent version of the Internet Protocol designed to replace IPv4, addressing the issue of IP address exhaustion with a vastly larger address space. It also introduces improvements in areas such as routing and network autoconfiguration, enhancing overall internet scalability and efficiency.
Network Address Translation (NAT) is a method used in networks to modify network address information in IP packet headers while in transit, allowing multiple devices on a local network to share a single public IP address. This process enhances security and conserves the limited number of available IPv4 addresses by hiding the internal IP addresses from external networks.
Concept
Subnetting is a technique used in IP networking to divide a larger network into smaller, more manageable subnetworks, enhancing both performance and security. It optimizes the use of IP addresses and reduces network congestion by localizing traffic within subnets.
The Domain Name System (DNS) acts as the phonebook of the internet, translating human-friendly domain names into IP addresses that computers use to identify each other on the network. It is a hierarchical and decentralized naming system that ensures efficient and reliable access to websites and online services.
The Internet Assigned Numbers Authority (IANA) is a crucial entity responsible for the global coordination of the DNS Root, IP addressing, and other Internet protocol resources. It ensures the stable and secure operation of the Internet by managing unique identifiers and facilitating the smooth operation of the global Internet infrastructure.
Concept
Routing is the process of selecting paths in a network along which to send data packets, ensuring efficient and reliable communication between devices. It involves the use of algorithms and protocols to determine the best path based on factors like network topology, traffic load, and link costs.
Network security involves implementing measures to protect the integrity, confidentiality, and availability of computer networks and data. It encompasses a variety of technologies, devices, and processes to defend against unauthorized access, misuse, malfunction, modification, destruction, or improper disclosure of network resources.
Network Address Translation (NAT) is a method used in routers to remap IP addresses by modifying network address information in the IP header of packets while they are in transit. This technique enables multiple devices on a local network to be mapped to a single public IP address, conserving global address space and enhancing security by masking internal IP addresses.
Session Traversal Utilities for NAT (STUN) is a network protocol that allows devices behind a NAT (Network Address Translation) to discover their public IP address and the type of NAT they are behind, facilitating peer-to-peer communication. It is crucial for applications like VoIP and video conferencing, where direct communication between clients is necessary despite NAT restrictions.
Port forwarding is a networking technique that allows external devices to access services on a private network by redirecting communication requests from one address and port number to another. It's crucial for enabling remote access to networked devices and services, often used in gaming, hosting servers, and accessing home security systems remotely.
