IP router: A device that performs IP routing. A physical device with roles defined by the IP protocol, including connecting LANs and WANs using its physical interfaces, and to route (forward) IP packets that come in any interface out the correct outgoing interface. IP address: A 32-bit binary number, often written in the DDN format that hosts use as their unique identifier in a TCP/IP network, much like a postal mailing address in the postal system Routing table: A list of IP routes used by an IP router when making routing decisions about where to forward an IP packet. IP network: When discussing IP addressing, this term refers to a group of IP addresses as defined by class A, B, or C rules. Also called a classful network ID
Dynamic Host Configuration Protocol: A TCP/IP protocol that uses a client-and-server model of communication, with messages that allow a client to ask the server to loan or lease to the client the use of an IP address for some period.
IP routing: The process of forwarding an IP packet from end to end through a TCP/IP network, as well as the logic used on an individual host or router as its part of the forwarding of the packet to its end destination. IP route: One entry in an IP routing table that lists some potential destination (usually a network ID or subnet ID) as forwarding instructions, including the interface out which the router should forward the IP packet
IP subnetting: The process of taking a class A, B, or C IP network and subdividing it into a number of smaller groups of addresses (subnets).
Default router: A host IP setting that refers to the IP address of some router, on the same subnet as the host, to which the host sends IP packets when the destination is on some other subnet
Address Resolution Protocol: A protocol that allows an IP host on a LAN to discover the MAC address of another host on the same LAN.

Unit 8 Lab 8.1: IP Addressing and Classes
Exercise 8.1.1
Use the IPCONFIG command on your Windows machine to identify the IP address and subnet mask used for your computer. What class of address is it? Are you able to identify it based on the first octet, by the subnet mask, or both? (If the subnet mask does not match the expected class from the IP address, choose the class based on the subnet mask.) Is your IP address part of the private address block? ITS A CLASS C starts with 192 it’s in a private network

Exercise 8.1.2
Does the use of subnet masking invalidate any of the class-full address assignments in IPv4, or does it expand the addressing capabilities while upholding the class rules for older addresses? Use your textbook and Internet research to justify your answer. IT actually expands and makes it so that they are not too many wasted addresses in networks.
Unit 8 Lab 8.2: Assigning Static IP Addresses
Exercise 8.2.1
How does the practice of assigning static IP addresses on a home or small office network make troubleshooting problems on the network easier? Use your textbook and Internet research to support your answer. It helps you pinpoint the proper when troubleshooting a particular issue using a static ip can dial into the computer that is having the issue.

Exercise 8.2.1 When would assigning static IP addresses be too cumbersome to be practical? What is the benefit of allowing hosts to dynamically acquire IP addresses through Dynamic Host Configuration Protocol (DHCP)? So you do not have to worry about setting up IPS to each individual machine or computer it is automatically done for by default done by a programmer
