MAN0148 rev 5
In CIDR notation, /16 means that 16 of these bits represents the subnet, and the remainder specifies the
host:

DEFAULT GATEWAY
Devices on the same subnet can address IP packets to each other without using a router device.
To communicate with devices on another subnetwork, the traffic must be routed through a router
device’s WAN port. When a device needs to communicate with an IP address that is not on the same
network, it sends the packet to the Default Gateway, which is usually the subnet’s Router.
Note: Some BACnet services use “broadcasts” (e.g. “Who-Is”). On a LAN with standard routers, these
broadcasts are “blocked”. As a result, BACnet broadcasts are limited to the IP Subnet of the BACnet
device. With a BACnet/IP network of 2 or more IP subnets, a device that can act as a BACnet/IP
Broadcast Management Device (BBMD) must be used.
