Hands$-$On Project $6-8$: Working with IPv$6$

Time Required: $15$ minutes

Objective: Use ipconfig and ping with IPv$6$ and change an IPv$6$ interface address.

Required Tools and Equipment: Net$-xx,$ and the address of another computer with an IPv$6$ address

Description: Your company plans to move to IPv$6.$ Because you haven't used IPv$6,$ you want to become comfortable using

common tools, such as ipconfig and ping.

Log on to Net$-$XX as NetAdmin, and open an elevated $($admin$)$ command prompt window, if necessary.

$2.$Type ipconfig and press Enter. Find the output line starting with "Link$-$local IPv$6$ Address." Notice that the

assigned address starts with fe$80$:: The fe$80$ indicates a link$-$local IPv$6$ address, and the :: indicates a string of $0$

values $-$ in this case, three consecutive $0$ values. The rest of the address $(64$ bits$)$ has been assigned randomly by

Windows.

$3.$Type ping ::$1$ and press Enter. Windows replies because you just pinged your own computer. Type ping $-$a ::$1$

and press Enter. The $-$a option tells Windows to display the hostname for the ::$1$ address, which is the name of your

computer.

$4.$Type ping $2001$:db$8$: $xx($replacing $xx$ with the address of another computer on the network$)$ and press Enter.

You should get a reply from the other computer. Type ping $-6$ Net$-xx($replacing $xx$ with the name of another

computer on the network$)$ and press Enter. The $-6$ option tells ping to use IPv$6$ addresses. You should get a reply

from the other computer, but it will probably come from the other computer's link$-$local $($fe$80)$ address.

$5.$Type getmac and press Enter to display your computer's MAC address. Make a note of this address:

$6.$Type netsh interface ipv$6$ set global randomizeidentifiers$=$disabled and press Enter. The interface is now using

the EUI$-64$ format to assign the link$-$local IPv$6$ address.

Type ipconfig and press Enter. Notice that the last $64$ bits of the IPv$6$ address now look like your MAC address,

with the addition of fffe after the first $24$ bits and $02$ instead of the first $00$ of your MAC address.

Close the command prompt window, and log off.
