Appendix C IP Addresses and Subnetting address to computer A or setting computer A to obtain an IP address automatically. Figure 157 Conflicting Computer IP Addresses Example Conflicting Router IP Addresses Example Since a router connects different networks, it must have interfaces using different network numbers. For example, if a router is set between a LAN and the Internet (WAN), the router's LAN and WAN addresses must be on different subnets. In the following example, the LAN and WAN are on the same subnet. The LAN computers cannot access the Internet because the router cannot route between networks. Figure 158 Conflicting Computer IP Addresses Example Conflicting Computer and Router IP Addresses Example More than one device can not use the same IP address. In the following example, the computer and the router's LAN port both use 192.168.1.1 as the IP address. P-663HN-51 User's Guide 263

Since a router connects different networks, it must have interfaces using different
network numbers. For example, if a router is set between a LAN and the Internet
(WAN), the router’s LAN and WAN addresses must be on different subnets. In the
following example, the LAN and WAN are on the same subnet. The LAN computers
cannot access the Internet because the router cannot route between networks.

Conflicting Computer and Router IP Addresses Example
More than one device can not use the same IP address. In the following example,
the computer and the router’s LAN port both use 192.168.1.1 as the IP address.
