Default Gateway - Keysight P Series Installation Manual

When written in binary, subnet masks usually become several 1s followed by
several 0s.
For example:
The subnet mask can be used with a device's IP address to determine the address
of the subnet that the device is on. To do this, you perform a logical AND of the
subnet mask and the IP address. (A logical AND combines two binary numbers
into a single number. The new number contains 1s in positions where both
numbers had 1s, and 0s everywhere else.)
For example, if a device has an IP address of 192.168.12.34 and the subnet mask
255.255.255.0 then:
The device is on the subnet with the 192.168.12.0 address.
A device with the IP address 192.168.12.100 is on the same subnet as the above
device with the IP address 192.168.12.34 (the 192.168.12.0 subnet), but a device
with an IP address of 192.168.100.34 is on a different subnet (the 192.168.100.0
subnet).

Default gateway

The default gateway is used by a device to communicate with devices that have IP
addresses that are on different subnets. This would usually be the IP address of
the router that connects the device's subnet to the rest of the network.
