computer B which is a DHCP client. Neither can access the Internet. This problem can be solved by
assigning a different static IP address to computer A or setting computer A to obtain an IP address
automatically.
Figure 111
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.

Conflicting Router 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. The computer cannot access the
Internet. This problem can be solved by assigning a different IP address to the computer or the
router’s LAN port.
