TCPIPprotokollide

TCPIPprotokollide refers to the collection of networking protocols that underlie Internet communications, commonly known as the TCP/IP protocol suite. The suite specifies how data is formatted into packets, addressed, transmitted, routed, and received by hosts and routers across diverse networks. It is designed to be scalable, interoperable, and capable of operating over a wide range of physical and link-layer technologies.

The model is often described as four layers: link, internet, transport, and application. The internet layer defines IP addressing and routing; the transport layer provides end-to-end communication with TCP, which is reliable and connection-oriented, and UDP, which is simpler and best-effort. The application layer encompasses protocols used by software applications, such as HTTP, HTTPS, DNS, SMTP, and FTP. At the edge, ARP maps IP addresses to hardware addresses on local networks; DHCP assigns IP configuration; ICMP supports error reporting and diagnostics.

TCPIPprotokollide emerged in the 1970s from the ARPANET project and was standardized by the Internet Engineering Task Force (IETF). Notable milestones include IPv4, TCP, and later IPv6, with RFCs that define each protocol and its behavior. The suite is continually updated to accommodate new technologies and security requirements.

Today, TCP/IP forms the core of global data communication, enabling scalable routing and interoperability across diverse networks and devices. While IPv4 remains widespread, IPv6 is increasingly deployed to address address space growth and efficiency. Security considerations include the use of TLS or DTLS for application-layer encryption, IPsec for network-layer security, and best practices for securing endpoints and services. Together, these protocols enable the Internet and private networks to function with standardized addressing, routing, and service interfaces.
