"DHCP: let networks auto-assign IPs, so devices just work."

DHCP Practical Explained – Step-by-Step In this DHCP practical, we demonstrate how Dynamic Host Configuration Protocol (DHCP) automatically assigns IP addresses and other network parameters to devices in a network, reducing manual configuration and human errors. What is DHCP? DHCP is a network protocol that enables devices (clients) to automatically receive: IP address Subnet mask Default gateway DNS server information This allows hosts to join a network quickly without manual IP configuration. DHCP Components DHCP Server – Assigns IP addresses and network details DHCP Client – Requests IP configuration IP Address Pool (Scope) – Range of IP addresses available for assignment DHCP Working Process (DORA) The DHCP process follows four main steps, known as DORA: Discover The client broadcasts a DHCP Discover message to find available DHCP servers. Offer The DHCP server responds with an IP address offer and configuration details. Request The client requests the offered IP address from the server. Acknowledge The server confirms and assigns the IP address to the client. DHCP Practical Lab Setup In this practical: A DHCP server is configured with an IP pool Network parameters like gateway and DNS are defined A client device is connected to the network The client automatically receives an IP address from the DHCP server Verification Steps Check IP address assignment using commands like ipconfig or ifconfig Verify DHCP bindings on the server Test connectivity using ping Benefits of DHCP Eliminates manual IP configuration Reduces configuration errors Simplifies network management Ideal for large and dynamic networks Conclusion This DHCP practical shows how DHCP simplifies IP address management by automatically assigning network settings, making it an essential protocol in modern networking.
