This chapter discusses how to configure IP on the ZyXEL Device.
10.1 Factory Ethernet Defaults
The Ethernet parameters of the ZyXEL Device are preset in the factory with the following values:
1IP address of 192.168.1.2
2Subnet mask of 255.255.255.0 (24 bits)
These parameters should work for the majority of installations.
10.2 TCP/IP Parameters
10.2.1 WAN IP Address Assignment
Every computer on the Internet must have a unique IP address. If your networks are isolated from the Internet (only between your two branch offices, for instance) 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.
Table 42 Private IP Address Ranges
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.
