shleases - Displays a DHCP client's IP address leases.
The shleases command reads the file that contains information about a client's leases and displays its contents on stdout. By default this file is /etc/join/leases. There are as many leases as there are interfaces which JOIN has configured. A lease is identified by the name of the interface (for example, ln0) and the IP address assigned to it. It is characterized by a start time, an expiration time, and the IP address of the server which granted the lease.
