Hostadresse

Hostadresse is a German term that translates to "host address" in English. It refers to the unique identifier of a device or a service connected to a computer network. This address is crucial for network communication, allowing data packets to be routed to their intended destination.

There are two primary types of host addresses commonly encountered: IP addresses and MAC addresses. An IP address, such as 192.168.1.1, is a logical address used at the network layer of the OSI model. It can be dynamic, assigned by a DHCP server, or static, configured manually. IP addresses enable communication across different networks, including the internet.

A MAC address, on the other hand, is a physical or hardware address assigned by the manufacturer of a network interface controller (NIC). It is a unique, globally recognized identifier, typically represented as a series of hexadecimal digits separated by colons or hyphens, like 00:1A:2B:3C:4D:5E. MAC addresses operate at the data link layer and are primarily used for local network communication within a subnet.

When a device sends data, it uses the host address of the destination to ensure the information reaches the correct recipient. Network devices like routers and switches use these addresses to make forwarding decisions. Understanding host addresses is fundamental to comprehending how networks function and how devices communicate with each other.
