An IP address that does not change.

static IP address

32

a system of computers,peripherals, terminals, and databases connected by communications lines

Network

33

A geographically close set of computers connected on a single network and using the same communication device

LAN

34

It can be as small as a home network with 2 computers, or anoffice with hundreds of computers that share access to printers, programs and a connection to theinternet.

LAN

35

A group of computersgeographically far apart, but areconnected.

WAN

36

Uses a public network, such as the internet, to establish a secure connection to an organization’s private network

VPN

37

A technique by which several hostsor computers share a single IPaddress for access to the Internet.

(NAT) Network Address Translation

38

This enables a LAN to use one setof IP addresses for internal trafficand a second set of addresses forexternal traffic, and provides atype of firewall by hiding internalIP addresses.

(NAT) Network Address Translation

39

Similar to NAT, but a more specific tool. It forwards requests for a particular IP port pair to another IP port pair

(PAT) Port Address Translation

40

This feature is commonly used onpublicly connected hosts to makean internal service available to alarger network.

(PAT) Port Address Translation

41

It is the concept of partitioning large networks into smaller segments.

Subnetworking, or subnetting

42

A portion of a network that shares a common address component..

Subnet

43

On TCP/IP networks, they are defined as all devices whose IP addresses have the same prefix

subnets

44

Look at this IP address. 150.215.017.009What do the first two numbers (150.215) represent?

They define the network

45

Look at this IP address. 150.215.017.009What do the last two numbers (017.009) represent?

They define a device or a particular host on the network

46

(the lowest in value) this IP addressencompasses the entire subnetwork.

Network IP

47

This IP address is used on customer's equipment.

Routable IP

48

This address (the highest in value)- identifies all hosts/devices on the LAN.

Broadcast IP

49

This subnet is for customers with 1 Static IP (one static, publicly routable IP address)

/30 subnet

50

The /30 subnet mask is

255.255.255.252

51

How many IP addresses are in a /30 subnet mask?

4

52

This Subnet is for customers with five Static IPs (five static, publicly routable IP address)

/29 subnet

53

The /29 Subnet uses how many IP addresses?

8

54

The /29 subnet mask is

255.255.255.248

55

This Subnet is for customers with 13 Static IPs (13 static, publicly routable IP addresses)

/28

56

How many IP Addresses does a /28 Subnet use?

16

57

The /28 subnet mask is

255.255.255.240

58

This allows users to privately share information over public communication

VPN / Virtual Private Network

59

What are the two gateway configuration options for a customer with a VPN endpoint?

1. Assign a Static IP to the customer's device2. Configure Port Forwarding on the IP Gateway

60

software/hardware used to preventunauthorized access from a computer system or network ofcomputer systems

Firewall
