IP Addresses, Subnets, & Subnet Masks
The factory assigns an IP address of 192.168.10.40 and a subnet
mask of 255.255.255.0 to each controller. Before adding the
controller to your network, assign it an IP address and subnet
mask appropriate for your network.
Caution — Talk with your Network Administrators before
assigning an IP address or subnet mask to a controller. They
can provide you with an available IP address, as well as which
subnet mask is appropriate for your particular network
configuration.
Isolate the ACR9000 controller and related devices on their
own subnet. The high-volume traffic on networks can affect
the ACR9000 controller's performance. A closed network
restricts the flow of traffic to only the controller and related
devices.
The IP address and subnet mask you assign each controller
determines to which subnet each controller belongs. To manage
the flow of data across a network, it can be divided into subnets
smaller networks within a network to provide more efficient
delivery of data.
IP Addresses
An IP address is an identifier for a device on a TCP/IP network.
Every device connected to the Internet must use a unique IP
Address.
The IP address is comprised of a 32-bit binary address that is
subdivided into four 8-bit segments known as octets. Because
people do not generally think in binary, the address is expressed
in dotted decimal format. Each binary octet is converted to a
decimal number ranging from 0 to 255, with each octet
separated by a decimal point. For example, an IP address in
dotted decimal format looks like the following:
192.168.10.120
