Configuring Alternate Private IP Addresses
Only IPv4 connections have alternate configurations. When you use
DHCP with an IPv4 connection, an automatic private IP address is
assigned when the DHCP server can’t be reached during startup or when
the current IP address lease expires. The automatic private IP address
is in the range 169.254.0.1 to 169.254.255.254, with a subnet mask of
255.255.0.0. Because the automatic private IP address configuration does
not include default gateway, DNS, or Windows
Internet Naming Service (WINS) server settings, a computer using the
alternate IP addressing is isolated on a separate network segment in the
Automatic Private IP Addressing (APIPA) range.
If you want to ensure that a computer uses specific IP address and
network configuration settings when no DHCP server is available, you
need to specify an alternate configuration. One of the key reasons for
using an alternate configuration is to accommodate mobile
device users who take their computers home from work. In this way, the
user’s mobile device can be configured to use a dynamically assigned IP
address at work and an alternate IP address configuration at home.
Before you get started, you might want to ask users for their home
networking settings, including the IP address, gateway, and DNS server
addresses required by their Internet service provider (ISP).
To configure alternate private IP addresses, complete the following steps:
-
In Control Panel, tap or click View Network Status And Tasks under the Network And Internet heading.
-
In the left pane in Network And Sharing Center, tap or click Change Adapter Settings.
-
Network Connections displays a list of all network connections
configured for use on the computer. Press and hold or right-click the
connection you want to configure, and then tap or click Properties.
-
Double-tap or double-click Internet Protocol Version 4 (TCP/IPv4) to
open the Internet Protocol Version 4 (TCP/IPv4) Properties dialog box.
You can also select Internet Protocol Version 4 (TCP/IPv4) and then tap
or click Properties.
-
If you have already configured the adapter to obtain an IP address
automatically, you should be able to tap or click the Alternate
Configuration tab, as shown in Figure 3.
-
On the Alternate Configuration tab, select the User Configured
option. Then, in the IP Address text box, type the IP address you want
to use. The IP address you assign to the computer should be a private IP
address, and it must not be in use anywhere else at the time the
settings are applied. Private IP addresses are normally in the range
10.0.0.1 to 10.255.255.254, 172.16.0.1 to 172.31.255.254, or 192.168.0.1
to 192.168.255.254 (excluding IP addresses reserved for network IDs and
broadcasts).
-
The Subnet Mask ensures that the computer communicates over the
network properly. Windows 8 should insert a default value into this box
for the subnet mask. If the network doesn’t use subnets, the default
value should suffice. However, if the network does use subnets, you need
to change this value as appropriate for the target network.
-
If the computer needs to access other TCP/IP networks, the Internet,
or other subnets, you must specify a default gateway. Type the IP
address of the network’s default router in the Default Gateway box.
-
DNS servers are needed for domain name resolution. Type a preferred and an alternate DNS server address in the boxes provided.
-
If WINS is used on the network for compatibility with previous versions of Windows, configure a preferred and an alternate WINS server using the boxes provided.
-
When you’ve finished, tap or click OK twice, and then tap or click Close.
Connecting to Networked Projectors
Many meeting rooms and conference centers have networked projectors
that are used for making presentations. To use this type of projector,
you must connect your computer to the local area network (LAN) and then
access the projector over the network by using the Connect
To A Network Projector Wizard. This wizard walks you through the steps
of finding projectors on a network and establishing a connection.
Before a mobile device can use the wizard, you must add the Network Projection feature. To do this, follow these steps:
-
In Control Panel, tap or click Programs and then tap or click Turn
Windows Features On Or Off under the Programs And Features heading.
-
In the Windows Features dialog box, tap or click the Network Projection check box and then tap or click OK.
When you install the Network Projection feature, the Connect To A
Network Projector utility is added to the Apps screen under the Windows
Accessories heading. The utility also should be available on the Start
screen. Before giving a presentation, users might want to configure
standard settings for presentations that:
These settings are configured in the Presentation Settings dialog
box. When working with Mobility Center, you can open this dialog box by
tapping or clicking the Network Projector icon on the Presentation
Settings tile.
You can use the Connect To A Network Projector Wizard by following these steps:
-
Tap or click Connect To A Network Projector on the Start screen or Apps screen.
-
If you haven’t previously attempted to connect to a network projector and Windows
Firewall is active, tap or click Allow The Network Projector To
Communicate With My Computer. This allows the network projector to
communicate with the computer through Windows Firewall.
-
If you want to select from projectors
found on the local network, tap or click Search For A Projector. The
wizard searches for projectors on the network and returns its results
along with a list of any projectors you’ve recently used. Tap or click
the projector you want to use, provide the access password for the
projector if necessary, and then tap or click Next.
-
If you know the network address of the projector, tap or click Enter
The Projector Network Address. On the Enter The Network Address Of A
Network Projector page, type the network address of the projector, such
as http://intranet.cpandl.local/projectors/confb-proj1. Enter any required access password, and then tap or click Connect.
-
Once you’ve established a connection to the projector, tap or click Finish to exit the wizard and begin using the projector.
