+udhcp lease dump (dumpleases)
+----------------------------
+
+dumpleases displays the leases written out by the udhcpd server. Lease
+times are stored in the file by time remaining in lease (for systems
+without clock that works when there is no power), or by the absolute
+time that it expires in seconds from epoch. dumpleases accepts the
+following command line options:
+
+-a, --absolute		Interpret lease times as expiration time.
+-r, --remaining		Interpret lease times as remaining time.
+-f, --file=FILE		Read lease information from FILE.
+-h, --help 		Display help.
+
+Note that if udhcpd has not written a leases file recently, the output
+of may not be up to date.
