EXPLANATION
DHCP Dora process is handling by a SERVER called DHCP SERVER that dynamically distributes network configuration parameter, such as IP Addresses for interface or services. It is a Standardized network protocol used on INTERNET PROTOCOL in the network. About DHCP SERVER, it can be a ROUTER that SERVER enables computers to request IP Address and networking parameter automatically and no need manual configuration.
What is DHCP?
In any network, if a host wants to communicate with another host, then it must have a unique IP address for it. Whether it is a local area network or a wide area network. The work of DHCP is to assign an IP address to the hosts. DHCP is a client/server protocol. DHCP port number is 67 and 68. DHCP client work on port number 67 and DHCP server work on port number 68.DHCP work as a client – Server Model, here SERVER handling the clients. DHCP employs a connectionless service model using UDP (User Datagram Protocol). Two UDP port used in DHCP process, 67 UDP port is the destination port of a server and 68 UDP port used by the client.
DHCP SERVER – DHCP SERVER working in same networking it means it provides IPs in the same network. DHCP SERVER automatically provides the IPs to clients. DHCP server manages a pool of IPs & information about client such parameter DEFAULT GATEWAY, DOMAIN NAME, SERVER NAME, & TIME SERVER.
How does DHCP Dora process work?
DHCP operation divides into 4 phases.- Server Discovery
- IP Lease Offer
- IP Lease Request
- IP lease Acknowledgement
