DHCP stands for "Dynamic Host Configuration Protocol" or in Slovak "Protocol for dynamic host configuration". It is a network protocol used to automatically assign configuration information to devices that connect to a network. This information includes IP address, subnet mask, gateway, and other network settings.
How DHCP works:
Request: When a device (eg computer, smartphone) enters the network, it sends a DHCP request to obtain configuration information.
Provisioning: The DHCP server (the device in the network whose task is to provide IP addresses and configurations) will respond to the device with a DHCP reply (DHCP reply) containing the assigned configuration information.
Assignment: The DHCP server adds an IP address and other configuration data to the device. An IP address is often assigned temporarily (time-limited) and can change every time you connect.
Use of DHCP:
Home networks: DHCP is often used in homes and small businesses to automatically assign IP addresses to devices that connect to the network to simplify network configuration and management.
Corporate networks: In larger networks, DHCP is an important tool that allows you to efficiently manage the number of connected devices without manually assigning IP addresses.
Wi-Fi networks: In wireless networks such as public Wi-Fi hotspots or home wireless networks, DHCP is crucial for connecting new devices quickly and easily.
Server networks: In larger networks where there are multiple servers and services, DHCP can also provide other configuration data such as DNS server addresses and gateways.
Overall, DHCP allows devices to join the network without the need for manual configuration, simplifying the process of connecting and managing devices in networks of various sizes.
