Cisco Dynamic Host Configuration protocol Server Client Lease Type
1.3.6.1.4.1.9.10.102.1.4.4.1.4
The type of this address. Types are: (1) Static addresses defined by the server configuration. (2) Dynamic addresses defined by the server configuration AND actually assigned by the server. (3) Expired dynamic addresses, previously assigned by the server, and 'remembered' for subsequent assignment to the same host. (4) Addresses reserved (i.e., not assignable) by the server configuration. (5) Addresses previously assigned by the server, but temporarily or permanently removed from assignable state for some reason, e.g., the server received an ICMP ECHOREPLY for the IPv4 address or a DHCPDECLINE message has been received for the IPv4 address.
