Subnet Addressing
A Subnet Mask is used to determine to which subnet an IP address belongs.
An IP address has two components: the network address and the host
address. For example, assuming IP address 156.215.117.109 is part of a
Class B network, the first two numbers (156.215) represent the Class B
network address and the second two numbers (117.109) identify a specific
host on this network. See the Glossary for a description of a Class B
network.
For the subnet in the figure, an example IP address for E5810 #1 is
156.140.104.72, where 156.140 represents the network address and 104.72
represents the E5810 #1 host address. An example IP address for E5810 #2
is 156.140.104.75, where 156.140 represents the network address and
104.75 represents the E5810 #2 host address.
E5810 IP Address
Assignment
For the E5810 to operate on an Enterprise network, three addresses must
be identified: E5810 IP Address, Subnet Mask, and Default Gateway
Address.
If the Enterprise network supports Dynamic Host Configuration Protocol
(DHCP), the E5810 will automatically receive an IP address, Subnet Mask,
and Default Gateway from the DHCP Server. If the network does not support
DHCP, the E5810 IP address must be configured manually.
In addition, if the network supports Domain Name Service (DNS), an E5810
Hostname can be configured. This can be done in one of two ways:
„ The DNS Server IP Address is provided by the DHCP Server (this is
transparent to the user).
„ A DNS Server IP address is supplied by the System Administrator
and entered on the Configuring your E5810 LAN/GPIB Gateway page.
