(IP) Two types of IP addresses: the first one is the most common one, ____, and the second type is ____.
IPv4, IPv6
(IPv4) IPv4 is the _______ version of IP addresses.

(IP C&R) You also going to need to memorize the _______ ______ _____ for each of these classes.
default, subnet, masks,
(IP C&R) Now if you notice we skipped over the “___” _____. And that’s because this number cannot be used for a network. Because the number 127 address is reserved for ________ ________ functions.
127, range, internal, loopback
(Private I.P) Public I.P addresses are ________ __________ on the internet. Which basically means that if you have a Public I.P address, you have access to the internet.
publicly, registered
(Private I.P) But Private I.P addresses are different. A private I.P is not ________ __________. So you cannot directly access the internet with a _______ I.P.
publicly, registered, private
(Private I.P) let’s say you have a small business and you need 10 public IP addresses so your employees can access the internet. Now, you could contact your ISP and ask them for these additional IP addresses, but that would be very _________ and unnecessary. So, that’s where _______ __ addressing comes in.
expensive, private, IP
(Private I.P) In private IP addressing, you can create these 10 private IP addresses and just have one publicly registered IP address from your ISP. These 10 private IPs would then be translated into the one ______ __, so your employees can have access to the ________. This not only saves money but it also helps prevent having a shortage of public IP addresses.
public IP, internet
(Private I.P) The RFC-1918 standard created private IP addressing to prevent a shortage of ______ __ ________ available to ISPs and subscribers.
public, IP, addresses
(Private I.P) Private IP addresses are typically used on _____ ________ such as homes, schools, and businesses.
local, networks
(Private Ranges) These private IP ranges have three classes: Class A starts with the number __, Class B starts with the number ___, and Class C starts with the number ___.
10, 172, 192
(Subnetting) The word “subnet” is short for “__________,” which means a smaller network within a ______ one.
subnetwork, larger
(Subnetting) Subnetting is basically breaking down a large network into _______ ________ or subnets. It’s mainly done to make your network more __________.
smaller networks, manageable
(Subnetting) Subnetting is basically done by changing the _______ ______ ____, by borrowing some of the bits that were designated for hosts and using them to create subnets.

(Dyn IP AM) Every computer on the network has to have an IP address for _____________ purposes.
communication
(Dyn IP AM) There are two ways that a computer can be assigned an IP address. It can be done either by using a _______ IP or a ______ IP.
dynamic, static

managing, network
(Stat IP AM) You can also assign a computer with an IP address ________, and this is called a ______ __.
manually, static IP
(Stat IP AM) A static IP is where a user ________ assigns an __ _______ for the computer.

(Reserv DHCP) If you wanted a computer on your network to have a specific IP address all the time, you can create a ___________ on the DHCP server.
reservation
(Reserv DHCP) A reservation ensures that a specific computer or device, identified by its ___ _______, will always be given the same IP address when that computer accesses the DHCP server.
MAC, Address
(Reserv DHCP) Reservations are not typically given to regular computers; they are typically given to _______ _______ or _________ such as network printers and servers that require using the same IP address constantly.
special, devices, computers.
(Lease DHCP) Computers obtain an IP address from a ____ ______.

lease, day
(Lease DHCP) Typically, a DHCP server will _____________ _____ the IP address for you, so you won’t have to do anything or even notice that the IP address is being renewed.
automatically, renew
(DHCP Relay) A DHCP relay or IP helper is a service that is enabled on a router that will relay a ____ broadcast it receives and ________ it.
DHCP, forwards
(DHCP Relay) So now the computer will broadcast a request for an IP address, and once the DHCP relay on the router receives the broadcast, it will forward the broadcast to the DHCP server, and then the DHCP server will send the __ _______ back to the ________.
IP, address, computer
(TCP) Transmission Control Protocol is one of the ____ protocols used in a TCP/IP _______.
