A DHCP Server is a network server that automatically provides and assigns IP addresses, default gateways and other network parameters to client devices. It relies on the standard protocol known as Dynamic Host Configuration Protocol or DHCP to respond to broadcast queries by clients.
When your computer isn’t connected to a network, its DHCP client program assigns a random IP address to the computer. That IP address is useless because the PC isn’t connected to a network. But the random IP address confuses some users because it appears as though the computer has a legitimate IP address. It does not. Aug 08, 2018 · Dynamic Host Configuration Protocol (DHCP) is the configuration of your Internet Protocol (IP) address, subnet mask, DNS servers, domain name suffix and about 200 other possible options to let your computer communicate with a network Example – Here is a topology in which there is a DHCP client having no IP address. There is a DHCP server having IP address 192.168.2.2 and there is a router in middle which we wants as DHCP relay agent has an IP address 192.168.1.1 on interface fa0/0 and 192.168.2.1 on interface fa0/1. Jul 25, 2020 · DHCP offers several benefits over static IP configuration: Reliable IP address management: DHCP minimizes configuration errors caused by manual IP address configuration, such as typographical errors, or address conflicts caused by the assignment of an IP address to more than one computer at the same time The Dynamic Host Configuration Protocol (DHCP) can help with the workload of configuring systems on a network by assigning addresses to systems on boot-up automatically. It also provides a central database of devices that are connected to the network and eliminates duplicate resource assignments.

DHCP Simplifies Network Administration Dynamic addressing simplifies network administration because the software keeps track of IP addresses rather than requiring an administrator to manage the task. This means that a new computer can be added to a network without the hassle of manually assigning it a unique IP address.

If DHCP client determines the offered configuration parameters are different or invalid, it sends DHCP decline message to the server .When there is a reply to the gratuitous ARP by any host to the client, the client sends DHCP decline message to the server showing the offered IP address is already in use.
DHCP Poisoning | Ethical Hacking DHCP Poisoning. Introduction. Dynamic Host Configuration Protocol (DHCP) is used to assIP's DHCP-enabled clients. The server holds valid TCP/IP configuration parameters, valid IP addresses and time period of the lease offer. When a client needs an IP, it sends a request to the DHCP server.
