Chapter 8 LAN Setup
8.2.1.1  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:
• 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 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.
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.
8.2.2  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 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 probably adequate for most 
networks, unless you have an unusual network topology.
Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the difference being that 
RIP-2B uses subnet broadcasting while RIP-2M uses multicasting.
