Conflicting Computer IP Addresses Example

More than one device can not use the same IP address. In the following example computer A has a

static (or fixed) IP address that is the same as the IP address that a DHCP server assigns to

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 95 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 96 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.
