    V-3. Glossary Default Gateway (Wireless bridge): Every non-access point IP device needs to configure a default gateway’s IP address. When the device sends out an IP packet, if the destination is not on the same network, the device has to send the packet to its default gateway, which will then send it out towards the destination.

Therefore sometimes a network mask can also be described simply as “x” number of leading 1’s. When both are represented side by side in their binary forms, all bits in the IP address that correspond to 1’s in the network mask become part of the IP network address, and the remaining bits correspond to the host ID.
