Understanding IP Addressing  B-7
Technical note on subnet masking
Note: The IP address supplied by the Netopia R6000 Series will be a unique number. You may want to replace 
this number with a number that your ISP supplies if you are configuring the router for a static IP address. 
However, the Netopia R6000 Series and all devices on the same local network must have the same subnet 
mask. If you require a different class address, you can edit the IP Mask field to enter the correct address. Refer 
to the table below. 
Configuration
This section describes the specific IP address lease, renew, and release mechanisms for both the Mac and PC, 
with either DHCP or MacIP address ser ving.
DHCP address serving
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-based computer.
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.
