netmask
Combined with the IP address, the IP Subnet Mask allows a device to know which other addresses are local
to it, and which must be reached through a gateway or router.
A number that explains which part of an IP address comprises the network address and which part is the host
address on that network. It can be expressed in dotted-decimal notation or as a number appended to the IP
address. For example, a 28-bit mask starting from the MSB can be shown as 255.255.255.192 or as /28
appended to the IP address.
Network Address Translation
Sometimes referred to as Transparent Proxying, IP Address Overloading, or IP Masquerading. Involves use
of a device called a Network Address Translator, which assigns a contrived, or logical, IP address and port
number to each node on an organization's internal network and passes packets using these assigned
addresses.
