What is the Full Form of DHCP?
DHCP stands for Dynamic Host Configuration Protocol. This tech term might sound a bit daunting, but it’s actually a fundamental part of how our internet experience is smooth and hassle-free.
History of DHCP
The journey of DHCP began in the late 1980s. It evolved from an older protocol, BOOTP, which was developed to boot computers over a network. However, BOOTP had limitations in dynamic IP address management. DHCP emerged as a solution, introduced in 1993, designed to dynamically assign IP addresses and reduce manual configurations.
Various Types of DHCP
- Dynamic DHCP: The most common type, it assigns IP addresses dynamically from a pool, ensuring efficient utilization.
- Static DHCP: This type assigns a fixed IP address to a device based on its MAC address.
- Automatic DHCP: Similar to dynamic, but the device retains the same IP address once assigned, until the DHCP server resets.
Different Parts of the DHCP
- DHCP Server: The central unit that manages the distribution of IP addresses.
- DHCP Client: The device (like your laptop or smartphone) that requests an IP address.
- IP Address Pool: A range of available IP addresses that the server can assign.
- Lease Time: The duration for which an IP address is assigned to a device.
- DHCP Relay Agent: Helps in forwarding requests and responses between clients and servers across different networks.
