It is the responsibility of the user to choose an IP address lying within the valid
range of addresses associated to the IP network the MO-180 is to be connected to.
Currently, three classes of networks are commonly used. These networks are
distinguished by the number of bytes used to identify the network and also by the
numeric range used for the first octet.
-
Class A networks are identified by the first byte, which ranges from 1 to 126.
There is a total of 126 class A networks with a possible number of
hosts/clients of 16.5 million.
-
Class B networks are identified by the first two octets, the first of which ranges
from 128 to 192. There is a total of 16384 class B networks, with a total of
65534 hosts per network.
-
Class C networks are identified by the first three octets, the first of which
ranges from 192 to 223. There is a total of 2.1 million class C networks with a
maximum of 254 hosts or clients each.
IP addresses 224.x.y.z and above are reserved for special purposes such as
multicasting.
Network devices which are not connected to the outside world need not have
globally-unique IP addresses. Three reserved private network ranges of IP addresses
have been standardised:
-
Class A. Address range 10.0.0.0 to 10.255.255.255
-
Class B. Address range 172.16.0.0 to 172.31.255.255
-
Class C. Address range 192.168.0.0 to 192.168.255.255
Typically the network administrator will divide the private network into subnets.
For instance, many ADSL home routers use a default address range of 192.168.0.0 to
192.168.0.255.
Class C is the private address range we should usually default to when
connecting the MO-180 to an IP network.
The way the MO-180 operates inside an IP network is configured with the
following three parameters which can be found under the CONFIGURATION menu:
-
IP address. This 4-octet number is the IP address of the modulator discussed
above. By default the value programmed into the modulator is 192.168.29.5.
