Windows 95 workstation:
■
The Win95 workstation requests and renews its lease ever y half hour.
■
The Win95 workstation does NOT relinquish its DHCP address lease when the machine is shut down.
■
The lease can be manually expired using the WINIPCFG program, a command line program executable from
the DOS prompt or from the START:RUN menu, on a Windows 95 or 98 machine.
Windows 3.1 workstation (MSTCP Version 3.11a):
■
The Win3.1 workstation requests and renews its lease ever y half hour.
■
The Win3.1 workstation does NOT relinquish its DHCP address lease when the user exits Windows and
goes to DOS.
■
The lease can be manually expired by typing IPCONFIG/RELEASE from a DOS window within Windows or
from the DOS prompt.
Macintosh workstation (Open Transpor t Version 1.1 or later):
■
The Mac workstation requests and renews its lease ever y half hour.
■
The Mac workstation relinquishes its address upon shutdown in all but one case. If the TCP/IP control
panel is set to initialize at star tup, and no IP ser vices are used or the TCP/IP control panel is not opened,
the DHCP address will NOT be relinquished upon shutdown. However, if the TCP/IP control panel is opened
or if an IP application is used, the Mac WILL relinquish the lease upon shutdown.
■
If the TCP/IP control panel is set to acquire an address only when needed (therefore a TCP/IP application
must have been launched to obtain a lease) the Mac WILL relinquish its lease upon shutdown ever y time.
