在DHCPREQUEST或DHCPDISCOVER包的options部分中，以期望的租赁时间为其值。在

来自RFC 2131 Section 3.5：

In addition, the client may suggest values for the network address and lease time in the DHCPDISCOVER message. The client may include the 'requested IP address' option to suggest that a particular IP address be assigned, and may include the 'IP address lease time' option to suggest the lease time it would like.
