What is the method of categorizing IP addresses in order to distribute them called? (subnetting) Classless inter-domain routing (CIDR)
In a TCP/IP network, the IP address of the router that interconnects the LAN to a wider network (usually the internet) is called what? The Default Gateway
What is created by the DHCP server to allow a system requesting DHCP IP information to use that information for a certain amount of time? DHCP Lease

What is the portion of an IP address that defines a specific machine in a subnet? Host ID
What is a command-line utility for Linux servers and workstations that displays the current TCP/IP configuration of the machine, similar to IPCONFIG for windows system? IFCONFIG
What is the organization responsible for assigning public IP addresses? Internet assigned numbers authority (IANA)
What is the protocol in which addresses consist of four sets of numbers, each number being a value between 0 and 255, using a period to separate the numbers? Internet protocol version 4
What is the numeric address of a computer connected to a TCP/IP network, such as the internet called? IP Addressing
What is a command-line utility for windows that displays the current TCP/IP configuration of the machine; similar to unix/Linux’s IFCONFIG? IPCONFIG
What is a reserved IP address used for internet that is sometimes called the local host? Loopback address
What is the method of sending a packet in which the sending computer sends it to a group of interested computers called? Multicast
What is a number used in IP networks to identify the network on which a device or machine exists called? The Network ID
What is an agreement that governs the procedures used to exchange info between cooperating entities called? Protocol
What is the set of protocols that are commonly used together and operate at different levels of the OSI 7 layer model called? Protocol Suite
What is a list of paths to various networks required by routers called? (They can be built either manually or automatically btw) The Routing Table
What is the process of assigning IP addresses by manually typing them into a clients computer called? Static addressing
What is the value used in TCP/IP settings to divide the IP address of a host into its component parts? Subnet mask
What are the 2 component parts of subnet mask? network ID and host ID
What is it called when you take a single class of IP addresses and chop it into mutiple smaller groups? Subnetting

What is a loopback address primary used for? testing...it is not assigned to computers
Why is the address 250.250.250.255 not a valid IP address to assign in a windows based system? Because it has a 255 as part of its address, which is a reserved number for subnet masks

List the order in which packets are created and sent when a client requests an IP address from a DHCP server? DHCP discovery, DHCP offer, DHCP request, DHCP acknowledge
Is the address 255.255.255.255 a valid classful subnet mask? no
What is an example of a valid classful subnet mask? 255.255.255.240
