DHCP data
DHCP is the network protocol most client devices use to associate themselves with an IP network. Implemented via a DHCP server, which could be standalone or embedded in a router or other network appliance, DHCP provides network clients with critical network parameters including IP address, subnet mask, network gateway, DNS servers, WINS or other name servers, time servers (NTP), a host and domain name, and the address of other optional network services. DHCP logs show exactly which systems are connecting to a network, their IP and MAC addresses, when they connect and for how long. In the Common Information Model, DHCP data is typically mapped to the Network Sessions data model.
