DHCP Server Information

A.

A DHCP (Dynamic Host Configuration Protocol) server is a network service that automatically assigns IP addresses and other network configuration parameters to devices on a network. The type of information that resides on a DHCP server includes:

A. A list of the available IP addresses in a pool: DHCP servers typically have a pool of IP addresses that they can assign to devices on the network. These IP addresses are usually assigned dynamically, which means that they are leased to devices for a specific period of time. When a device requests an IP address from the DHCP server, the server checks its pool of available addresses and assigns an available address to the device.

B. A list of public IP addresses and their corresponding names: DHCP servers do not typically manage public IP addresses. Public IP addresses are assigned by Internet Service Providers (ISPs) and are used to connect devices to the internet. DHCP servers manage private IP addresses, which are used to connect devices on a local network.

C. Usernames and passwords for the end users in a domain: DHCP servers do not typically manage usernames and passwords for end users. Usernames and passwords are managed by authentication servers such as Active Directory or LDAP.

D. A list of statically assigned MAC addresses: DHCP servers can also be configured to assign IP addresses to devices based on their MAC addresses. This is known as static IP address assignment. In this case, the DHCP server maintains a list of MAC addresses and their corresponding IP addresses. When a device with a known MAC address requests an IP address, the DHCP server assigns the corresponding IP address to the device.

In summary, the information that resides on a DHCP server includes a pool of available IP addresses, a list of statically assigned MAC addresses, and DHCP configuration parameters such as subnet mask, default gateway, and DNS server information.
