VLAN implementations can affect IP addressing designs in several ways. First, since each VLAN typically has a different IP subnet assigned to it, the IP address range must be carefully planned to ensure proper segregation between the different VLANs. Also, since each VLAN must use a unique IP broadcast address, a VLAN implementation may require additional IP routing rules or configuration parameters which must be configured. Finally, VLAN–based network designs may change the way certain IP addresses are assigned and routed within the network; for example, certain IP addresses may have to be routed through specific VLAN gateways instead of through traditional routers.
