multi-homed host
A host that has more than one network interface connected to the same
network.
netmask
A mask used to determine the network address from a host address. A
netmask is composed of four integers in the range 0-255 separated by periods.
When a netmask is expressed in binary notation, it must be a contiguous
sequence of “ones” followed by a contiguous sequence of “zeroes” (for
example 255.255.128.0).
network address
A number that identifies the network in which a computer resides. A network
address is composed of four integers separated by periods. The first integer
must be in the range 0-223, the second and third integers in the range 0-255
and the fourth integer in the range 0-254 (for example 129.144.0.0).
network interface
An access point to a system on a network. Each interface is associated with a
physical device. However, a physical device can have multiple network
interfaces.
PPP
Point-to-Point Protocol. This protocol allows two computers to be connected
over a two-way communications link, such as a telephone line. The connection
is established as needed.

A default route does not contain a specific destination; it has a general
destination used for any destinations not specified in other routes.
router
A computer or other dedicated hardware that connects two or more networks
and routes data between them.
static router
A router that relies on manual addition of routes. Routing information is not
exchanged with other routers.
