Assigning static Internet information to your PCs
In some cases, you may want to assign Internet information to
some or all of your PCs directly (often called “statically”), rather than
allowing the Neobit 1012VAto assign it. This option may be
desirable (but not required) if:
 You have obtained one or more public IP addresses that
you want to always associate with specific computers (for
example, if you are using a computer as a public web
server).
 You maintain different subnets on your LAN (subnets are
described in Appendix A).
Before you begin, contact your ISP if you do not already have the
following information:
 The IP address and subnet mask to be assigned to each
PC to which you will be assigning static IP information.
 The IP address of the default gateway for your LAN. In
most cases, this is the address assigned to the LAN port on
the Neobit 1012VA. By default, the LAN port is assigned
this IP address: 192.168.1.1. (You can change this number,
or another number can be assigned by your ISP. See
Chapter 5 for more information.)
 The IP address of your ISP’s Domain Name System (DNS)
server.
On each PC to which you want to assign static information, follow
the instructions on pages 16 through 20 relating only to checking for
and/or installing the IP protocol. Once it is installed, continue to
follow the instructions for displaying each of the Internet Protocol
(TCP/IP) properties. Instead of enabling dynamic assignment of the
IP addresses for the computer, DNS server, and default gateway,
click the radio buttons that enable you to enter the information
manually.
Note
Your PCs must have IP addresses that place them in the same
subnet as the Neobit 1012VA’s LAN port. If you manually assign IP
information to all your LAN PCs, you can follow the instructions in
Chapter 5 to change the LAN port IP address accordingly.
