7.5 Technical Reference
This section provides some technical background information about the topics covered in this chapter.
LANs, WANs and the Zyxel Device
The actual physical connection determines whether the Zyxel Device ports are LAN or WAN ports. There
are two separate IP networks, one inside the LAN network and the other outside the WAN network as
shown next.
Figure 53 LAN and WAN IP Addresses
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
