DHCP events are structured to allow network defenders to track a given machine, by Media Access Control (MAC) address to an Internet Protocol (IP) address. Noting that DHCP IP addresses assign an IP address to a given MAC address for a specified lease period, the DHCP event tracks these elements.

Attributes
IPAddress	_ipAddress
String	clientMACAddress	The Media Access Control (MAC) address that was assigned an IP address during this DHCP event.
«baseType» Duration	leaseDuration	The time duration that the IP address has been assigned to the MAC address for.
