A four-byte number uniquely defining each host on the Internet. Ranges of
addresses are assigned by Internic, an organization formed for this purpose.
Usually written in dotted-decimal notation with periods separating the bytes
(for example, 134.177.244.57).
Internet Protocol Security. IPSec is a series of guidelines for securing private
information transmitted over public networks. IPSec is a VPN method
providing a higher level of security than PPTP.
Internet service provider.
The main internetworking protocol used in the Internet. Used in conjunction
with the Transfer Control Protocol (TCP) to form TCP/IP.
See local area network.
LAN. A communications network serving users within a limited area, such as
one floor of a building. A LAN typically connects multiple personal
computers and shared network devices such as storage and printers. Although
many technologies exist to implement a LAN, Ethernet is the most common
for connecting personal computers.
Media Access Control address. A unique 48-bit hardware address assigned to
every Ethernet node. Usually written in the form 01:23:45:67:89:ab.
Megabits per second.
See Most Significant Bit or Most Significant Byte.
See Maximum Transmission Unit.
The size in bytes of the largest packet that can be sent or received.
The portion of a number, address, or field that is farthest left when written as a
single number in conventional hexadecimal ordinary notation. The part of the
number having the most value.
See Network Address Translation.
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.
