Lesson 4: Understanding Internet Protocol
Terms in this set (68)
Internet Protocol Version 4 (IPv4)
the most frequently used communications protocol.
IP resides on the ___________ layer of the OSI model.
Classful Network Architecture
Broken down into five sections, three of which are commonly used by hosts on networks-Classes A, B, & C and is the IPv4 classification system.
The ________ octet of the IP address defines which class the address is a member of.
The term ________ is synonymous with "host."
Default Class A Subnet Mask
Default Class B Subnet Mask
Default Class C Subnet Mask
Used to communicate with all hosts on the network.
Transmitting data to multiple computers (or routers).
Class D Network
Used for multicasting.
occur when two computers are configured with the same IP address.
_____________ IP addresses are ones that are exposed to the internet; any other computers on the internet can potentially communicate with them.
__________ IP address are hidden from the Internet and any other networks.
Class A Range (Private IPv4 Address)
10.0.0.0 - 10.255.255.255
Class B Range (Private IPv4 Address)
172.16.0.0 - 172.31.255.255
Class C Range (Private IPv4 Address)
184.108.40.206 - 192.168.255.255
Automatic Private IP Addressing (APIPA)
If a windows client cannot get an IP address from a DHCP server and has not been configured statically, the __________ will auto-assign a number on this network.
The Class B network number used for Automatic Private IP Addressing (APIPA).
The first IP address of the device that a client computer will look for when attempting to gain access outside the local network.
This device could be a router, server, or other similar device; it is the device that grants access to the Internet or other networks.
DNS server address
the IP address of the device or server that resolves DNS addresses to IP addresses.
Network Address Translation (NAT)
The process of modifying an IP address while it is in transit across a router, computer, or similar device.
Port Address Translations (PAT)
Translates both IP addresses and port numbers.
In Subnetting, if the binary digit is a 1, then it is __________.
In Subnetting, if the binary digit is a 0, then it is __________.
The act of dividing a network into smaller logical subnetworks.
Classless inter-domain routing (CIDR)
A way of allocating IP addresses and routing Internet Protocol packets.
Variable-length subnet masking (VLSM)
Allows a network to be divided into different-sized subnets to make one IP network that would have previously been considered a class (such as Class A) look like Class B or Class C.
Address assigned to one interface of one host. ::/10 means that addresses starting with FE80, FE90, FEA0, and FEB0 are part of the range.
Address assigned to a group of interfaces on multiple nodes. Packets are delivered to the "first" or "closest" interface only.
Address assigned to a group of interfaces on multiple nodes. Packets are delivered to all interfaces.
Global Routing Prefix
This is the first three groups of numbers, and it defines the "network" of the address.
This defines the individual subnet of the network that the address is located on.
This is the individual host IP portion. It can be assigned to one interface or more than one interface, depending on the type of IPv6 address.
An IPv6 address can be abbreviated or __________ by removing unnecessary and /or leading 0s.
This is 40 bytes and contains the source and destination addresses plus other forwarding information.
Optional Extension Header
This incorporates options for special treatment of the packet, such as routing and security.
By default, this is 64 KB maximum, just like IPV4 packets. But this can be increased much further if jumbograms are used.
The Net Shell Command
a tool that administrators can use to configure and monitor Windows computers from the command prompt.
Dual IP Stack
Exists when there are two Internet Protocol software implementations in an operating system, one for IPv4 and another for IPv6.
Have the first 80 bits set to 0 (note the double colon), the next 16 set to 1 (shown as ffff), and the last 32 bits populated by the IPv4 address.
IPv6 packets can be encapsulated inside IPv4 datagrams.
Your client requires that you nstall 284 computers on a single IP network. Which IP class would be your best option?
Your boss wants you to set up three computers on a classful network with a default subnet mase of 255.0.0.0. What class does he want the computers to be set up on?
What is 249 equal to in binary?
What is 86 equal to in binary?
What is 199 equal to in binary?
You are trouble shooting a computer that cannot obtain the proper IP address from a DHCP server. When you run an ipconfig/all, you see that the computer has obtained the address 169.254.67.110 automatically. What has auto assigned an IP address the the computer?
You need to connect 802.11a, 802.11b, and 802.11n wireless networks together. What wireless tool will guarantee connectivity between these networks?
You have installed a device that has two IP addresses. One address, 220.127.116.11, is displayed to the Internet. The other address, 192.168.50.254, communicates with the LAN. What type of technology have you implemented?
What is the default subnet mask for a Class B network?
You have a host with the address of 18.104.22.168. To what class would this address be assigned?
For IPv4, what class is used for multicasting?
What is the maximum number of hosts you can use for each subnet that belongs to a class C address?
What type of address is 22.214.171.124?
What type of address is used to send a single set of packets to multiple hosts?
Which of the following is not a private address?
What type of address is 169.254.32.23?
The hose cannot find a DHCP server
You have a computer that cannot connect to a server. When you look at the IP configuration, the host has an address of 126.96.36.199. What is the problem?
What defines the nearest router for a host?
What server is used to translate host names to IP addresses?
What is used to remap private addresses to public addresses and back?
What do you call a smaller network that is part of a larger network?
How many bits is an IPv6 address?
A _____________ address is assigned by a DHCP server.
IPv4 Mapped Addresses
What IPv6 address incorporates IPv4?
