Private IP Addresses
Every machine on the Internet must have a unique address. If your networks are
isolated from the Internet, for example, 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:
isolated from the Internet, for example, 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
• 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 it can be assigned
from 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.

organization, you should consult your network administrator for the appropriate IP

Note: 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”.

7.6.5 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:
information with other routers. The RIP Direction field controls the sending and
receiving of RIP packets. When set to:
• Both - the ZyXEL Device will broadcast its routing table periodically and
incorporate the RIP information that it receives.
• In Only - the ZyXEL Device will not send any RIP packets but will accept all RIP
packets received.
• Out Only - the ZyXEL Device will send out RIP packets but will not accept any
RIP packets received.
• None - the ZyXEL Device 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 ZyXEL Device sends (it recognizes both formats when receiving).
RIP-1 is universally supported; but RIP-2 carries more information. RIP-1 is
