Review the different types of IPv6 addresses.

Match the IPv6 address with the correct type.

Part !: "#a$ine a %ost IPv6 &et'or( Interface and Address

Check PC IPv6 network address settings.

Part ): Practice IPv6 Address Abbreviation

Study and review the rules for IPv6 address abbreviation.

Practice compressing and decompressing IPv6 addresses.

Part *: Identify the %ierarchy of the IPv6 +lobal ,nicast Address &et'or( Prefi#

Study and review the hierarchy of the IPv6 network prefi.

Practice deriving network prefi information from an IPv6 address.

-ac(grond / 0cenario

!ith the depletion of the Internet Protocol version " #IPv"$ network address space and the adoption andtransition to IPv6% networking professionals must understand how both IPv" and IPv6 networks function.Many devices and applications already support IPv6. &his includes etensive Cisco device Internetwork'perating System #I'S$ support and workstation(server operating system support% such as that found in!indows and )inu.

&his lab focuses on IPv6 addresses and the components of the address. In Part *% you will identify the IPv6address types% and in Part +% you will view the IPv6 settings on a PC. In Part ,% you will practice IPv6 addressabbreviation% and in Part "% you will identify the parts of the IPv6 network prefi with a focus on global unicastaddresses.

Part 1: Identify the ifferent Types of IPv6 Addresses

In Part *% you will review the characteristics of IPv6 addresses to identify the different types of IPv6addresses.

0tep 1: evie' the different types of IPv6 addresses.

3n IPv6 address is *+4 bits long. It is most often presented as ,+ headecimal characters. 5achheadecimal character is the euivalent of " bits #" ,+ 7 *+4$. 3 non8abbreviated IPv6 host address isshown here/

!331:3-:3331:3333:3333:3333:3333:3331

3 hetet is the headecimal% IPv6 version of an IPv" octet. 3n IPv" address is " octets long% separated bydots. 3n IPv6 address is 4 hetets long% separated by colons.

3n IPv" address is " octets and is commonly written or displayed in decimal notation.

!77.!77.!77.!77

3n IPv6 address is 4 hetets and is commonly written or displayed in headecimal notation.

8888:8888:8888:8888:8888:8888:8888:8888

In an IPv" address% each individual octet is 4 binary digits #bits$. 9our octets euals one ,+8bit IPv"address.

11111111.11111111.11111111.11111111 9 !77.!77.!77.!77

In an IPv6 address% each individual hetet is *6 bits long. 5ight hetets euals one *+48bit IPv6 address.

1111111111111111 9 8888

1111111111111111.1111111111111111.1111111111111111.1111111111111111.

8888:8888:8888:8888:8888:8888:8888:8888

If we read an IPv6 address starting from the left% the f irst #or far left$ hetet identifies the IPv6 addresstype. 9or eample% if the IPv6 address has all :eros in the far left hetet% then the address is possibly aloopback address.

c. Click the &et'or( and 0haring 4enter icon.

d. 'n the left side of the window% click 4hange adapter settings. Eou should now see icons representingyour installed network adapters. Right8click your active network interface #it may be a Local Area

determine whether IPv6 is present% which indicates that it is installed% and if it is also check marked% whichindicates that it is active.

f. Select the item Internet Protocol >ersion 6 T4P/IPv6;and click Properties. Eou should see the IPv6settings for your network interface. Eour IPv6 properties window is likely set to Obtain an IPv6 addressato$atically. &his does not mean that IPv6 relies on the =ynamic Fost Configuration Protocol #=FCP$.Instead of using =FCP% IPv6 looks to the local router for IPv6 network information and then auto8configures its own IPv6 addresses. &o manually configure IPv6% you must provide the IPv6 address% thesubnet prefi length% and the default gateway.

&ote/ &he local router can refer host reuests for IPv6 information% especially =omain ?ame System#=?S$ information% to a =FCPv6 server on the network.

Part ): Practice IPv6 Address Abbreviation

In Part ,% you will study and review rules for IPv6 address abbreviation to correctly compress and decompressIPv6 addresses.

0tep 1: 0tdy and revie' the rles for IPv6 address abbreviation.

that each number% or character% in an IPv6 address is written in headecimal% which is euivalent to four bits.&he following is a typical global unicast address/

The net'or( portion/ !331:-:3331:A4A////

The host portion/ ////3333:3333:3333:3331

Most global unicast #routable$ addresses use a 6"8bit network prefi and a 6"8bit host address. Fowever% the

network portion of an IPv6 address is not restricted to 6" bits in length and its length is identified at the end ofthe address by slash notation% followed by a decimal number indicating its length. If the network prefi is (6"%then the network portion of the IPv6 address is 6" bits long from left to right. &he host portion% or interface I=%which is the last 6" bits% is the remaining length of the IPv6 address. In some cases% as with a loopbackaddress% the network prefi can be (*+4% or one hundred and twenty eight bits long. In this case% there are nobits left over for the interface identifier% and therefore% the network is restricted to a single host. Fere are someeamples of IPv6 addresses with different network prefi lengths/

+lobal nicast address: +22*/=

*; Interface I= #last 6" bits$

&he host portion of the IPv6 address is called the Interface I=% because it does not identify the actual host% butrather the hostKs network interface card. 5ach network interface can have multiple IPv6 addresses% andtherefore% can also have multiple interface I=s.
