•
Public IP Address
- An IP address for a resource in your
network that is published outside your network to the WAN.
•
Router
- A device that routes data between networks through IP
address information in the header of the IP packet. A router
forwards packets to other routers until the packets reach their
destination. The Internet is the largest example of a routed
network.
•
Subnet
- A portion of a network. Each subnet within a network
shares a common network address and is uniquely identified by a
subnetwork number.
•
Subnet Mask
- A 32-bit number used to separate the network
and host sections of an IP address. A subnet mask subdivides an
IP network into smaller pieces. An example of a subnet mask
might be 255.255.255.248 for subnet with only eight IP
addresses.
•
TCP/IP
- Transmission Control Protocol/Internet Protocol is the
basic communication protocol of the Internet. It supports sending
information in packets, and identifies each device with a unique
numeric IP address.
•
VPN
- A Virtual Private Network is a virtual network that encrypts
data and sends it privately over the Internet to protect sensitive
information.
•
WAN
- A Wide Area Network is a geographically distributed
network composed of multiple networks joined into a single large
network. The Internet is a global WAN.
