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 317

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.
