6.1.2 Private IP Addresses
Every machine on the Internet must have a unique address. If your networks are isolated from the Internet,
e.g., only between your two branch offices, you can assign any IP addresses to the hosts without problems.
However, the Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of IP
addresses specifically for private networks:
10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
You can obtain your IP address from the IANA, from an ISP, or have it assigned by a private network. If
you belong to a small organization and your Internet access is through an ISP, the ISP can provide you with
the Internet addresses for your local networks. On the other hand, if you are part of a much larger
organization, you should consult your network administrator for the appropriate IP addresses.
Regardless of your particular situation, do not create an arbitrary IP address;
always follow the guidelines above. For more information on address assignment,
please refer to RFC 1597, Address Allocation for Private Internets and RFC 1466,
Guidelines for Management of IP Address Space.
6.1.3 Factory Ethernet Defaults
The Ethernet parameters of the Prestige are preset in the factory with the following values:
IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits).
6.1.4 RIP Setup
RIP (Routing Information Protocol) allows a router to exchange routing information with other routers.
The RIP Direction field controls the sending and receiving of RIP packets. When set to:
1. Both - the Prestige will broadcast its routing table periodically and incorporate the RIP information
that it receives.
2. In Only - the Prestige will not send any RIP packets but will accept all RIP packets received.
