Why do you need DHCP server?

The primary reason DHCP is needed is to simplify the management of IP addresses on networks. No two hosts can have the same IP address, and configuring them manually will likely lead to errors.

What is the biggest benefit to using a DHCP server?

One of the biggest advantages of using the DHCP is that it allows the automatic management of IP addresses. In any network without DHCP, the user needs to set the IP address to each client manually. This IP address needs to be reconfigured when the client moves to a different network.

What if I dont have a DHCP server?

A DHCP server automatically sends the required network parameters for clients to properly communicate on the network. Without it, the network administrator has to manually set up every client that joins the network, which can be cumbersome, especially in large networks.

How many IP addresses can a DHCP server assign?

You could have DHCP assign up to 254 in one, and 254 in another, until you run out of addressable space, or the load on your server and/or network gets too much for infrastructure to reasonably handle.

How would a network benefit from the use of DHCP?

One main advantage of using DHCP is that DHCP servers greatly reduce the time required to configure and reconfigure computers on your network. For example, DHCP helps prevent address conflicts caused when the same IP address is mistakenly assigned to two hosts.

What happens if I turn DHCP off?

DHCP means Dynamic Host Configuration Protocol it is a service which assigns ip addresses automatically to devices which are connected in the network and requests for an ip. So if you disable DHCP in your router your devices will not get ip addresses and they will not be able to communicate in the network.

What is the DHCP server responsible for?

What are the disadvantages of a DHCP server?

As the DHCP servers have no secure mechanism for the authentication of the client so any new client can join the network. This posses security risks like unauthorized clients being given IP address and IP address depletion from unauthorized clients. The DHCP server can be a single point of failure if the network has only one DHCP server.
