Appendix B
:
An IP address with a host address portion of all 1's implies a "broadcast" to all devices
on the subnet. If the Instreamer ICE has an IP address of 192.10.0.40 and a netmask of
255.255.255.0, the broadcast address for this subnet is 192.10.0.255. No device on
the network, including the Instreamer ICE can have an IP address of 192.10.0.255.
The address 127.0.0.1 is also a special address that is called a "loopback" address. This is
not a valid address to assign to the Barionet.
B.4
Private IP addresses and the Internet
Because of the limited range of IP addresses in the most common version of the Internet
protocol
5
, a series of "private" IP address ranges have been defined that allow any number
of private networks to use the same range of IP addresses. These "private" IP ranges are
translated to one or more "public" IP addresses for access to the internet using a protocol
called "Network Address Translation" or NAT. Most modern routers used in small home or
office networks implement NAT so that a single public IP address can be shared by an entire
network of computers using a range of these private IP addresses.
The same principles apply to the assignment IP address, netmask, and gateway IP address
in a private network. The primary difference is that private network IP addresses don't have
to be unique across the entire internet, while public IP addresses must be unique.
If the network you're connecting your Instreamer ICE to is not connected to the internet, you
can choose any address range you like. However, if the network is, or will be connected to
the internet in the future, it's wise to use one of the private IP address ranges and a NAT-
capable router/firewall for connecting to the Internet. If you have questions about these
networks, and the appropriate address to assign to an Instreamer ICE, contact your network
administrator.
The table below shows the range of private IP addresses defined for each of the three
"classes" of private networks.
