Subnet Mask; Pinging For The Ip Address - Extron electronics DXP DVI Pro User Manual

Subnet Mask

The subnet mask is another 32-bit binary number that is used to "mask" certain bits of the
IP address. This provides a method of extending the number of network options for a given
IP address. It works by allowing part of the host identifier to be used as a subnet identifier.
It is important that you set the correct value for the subnet mask. The basic values depend
on the class of IP address being used (see
Class Name
Class A
Class B
Class C

Pinging for the IP Address

To access the DXP switcher via the Ethernet port, you need the switcher IP address. If the
address has been changed to an address comprised of words and characters, the actual
numeric IP address can be determined using the Ping utility. If the address has not been
changed, the factory-specified default is 192.168.254.254.
Ping can also be used to test the Ethernet link to the DXP switcher.
Ping to determine Extron IP address
The Microsoft Ping utility is available at the command prompt. Ping tests the Ethernet
interface between the computer and the DXP switcher. Ping can also be used to determine
the actual numeric IP address from an alias and to determine the web address.
Ping the switcher as follows:
1. From the Windows Start menu, select Run... . The Run window opens.
2. In the Open text field, enter command.
3. Click OK. A command window opens.
4. At the command prompt, enter ping
similar to figure 121.
The line Pinging ... reports the actual numeric IP address, regardless of whether
you entered the actual numeric IP address or an alias name.
