Prestige 782R G.SHDSL Router
Internet Access 3-3
If you have a single user account, the ISP will assign you a dynamic IP address when the connection is
established. You must enable the Single User Account feature of the Prestige and choose a network number
from 192.168.0.0 to 192.168.255.0. This block of addresses has been reserved for private by The Internet
Assigned Number Authority (IANA); please do not use any other number.
For example, the IP address 192.168.1.0, covers 254 individual addresses, from 192.168.1.1 to
192.168.1.254 (zero and 255 are reserved). The first 3 numbers (192) are the network number while the last
number (0) identifies an individual computer on that network.
The subnet mask specifies the network number portion of an IP address. Your Prestige will compute the
subnet mask automatically based on the IP address that you typed. You do not need to change the subnet
mask computed by the Prestige unless you are instructed to do otherwise.
Private IP Addresses
Every computer 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, it is recommended that you choose your network number from following three blocks of IP
addresses that the Internet Assigned Numbers Authority (IANA) has reserved the specifically for private
networks:
10.0.0.0 to 10.255.255.255
172.16.0.0 to 172.31.255.255
192.168.0.0 to 192.168.255.255
Your IP address can be assigned by the IANA, an ISP, or by a private network. Small organizations whose
Internet access is through an ISP, will be given Internet addresses for local networks by the ISP. Larger
organizations should consult the network administrator for the appropriate IP addresses.
Regardless of your circumstances, 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.
3.2.6 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 Both, the Prestige will
broadcast its routing table periodically and incorporate the RIP information that it receives; when set to
None, it will not send any RIP packets and will ignore any RIP packets received.
The Version field controls the format and the broadcasting method of the RIP packets that the Prestige
sends (it recognizes both formats when receiving). RIP-1 is universally supported; but RIP-2 carries more
information. RIP-1 is probably adequate for most networks, unless you have an unusual network topology.
