What is an IP Address?
An IP address
1
is a 32-bit number denoted by four 8-bit values (octets) separated by periods:
192.168.1.87, for example. Usually, the first three octets form a subnet and the last octet is a
unique device identifier, within the bounds of the subnet. Each octet can have a value from 1 to
254. (The values 0 and 255 are reserved for other purposes.)
(See What is a Subnet? on page 140.)
For example, if a device’s IP address is 192.168.1.87, the router’s subnet is 192.168.1 and its
unique device identifier is 87.
In addition to IP addresses, many networks support the use of plain-language (English, Spanish,
etc.) names for devices on the network. These are usually managed by a name server using DNS
(Dynamic Name Service), WINS (Windows Integrated Name Service), or similar.
Miranda routers and MRC do not support plain text naming. The router network should be a
closed, private network.
Unless otherwise specified by your system administrator, Miranda suggests the following IP
address settings for their routers’ control cards:
The configuration PC should be set to the following IP address: 192.168.1.19. If you specify a
different subnet, use a unique address on the same subnet that the routers use.
If your configuration PC is already connected to a network, it might be impractical or undesir-
able to change its IP address. If this is your situation, we recommend installing a second network
card in your PC that is connected to the routers’ subnet. Doing so preserves your existing
network settings and allows you to create a fixed IP address, and any other required network
settings, for routers.
Consult your system administrator before adding a NIC (network interface card) to any PC
already set up with a network connection. The new NIC may interfere with Windows bindings or
other network settings if it is not added correctly.
You can use the ‘Network Interfaces’ button of MRC’s ‘NVISION Series Products’ page to obtain a
report of the NICs in your configuration PC.
What is a Subnet?
A subnet is an identifiable and distinct part of a network that allows a large network to be orga-
nized into smaller sections. For example, a subnet may represent all the machines at one
geographic location or on the same local area network (LAN).
