Activity Guide - DNS
Log on to Code Studio and
join the Internet Simulator. You are going to interview/have a conversation
with a classmate using only the Internet Simulator. We’ve created a list of
interview questions (on the next page) and you should both jot down each other’s
working, if your teacher taps you and your partner, you both MUST disconnect
and reconnect from the simulation. This is to simulate changing IP addresses.
Even though your IP address will change, your hostname will stay the same, so
you’ll need to re-join a router and ask the DNS for your partner’s new IP
address in order to continue having your conversation!
with the DNS
To begin, click over to
the “DNS” tab to see all the hostnames of people on the router. You will see
the address of the DNS (always 15) but will not see an address for anyone else
on the router.
server responds to a text protocol that will give you someone’s IP address.
Type the IP address of the DNS into the “To” field, then use the following
protocol to retrieve the IP address.
The protocol is: GET
For example: GET
can request the IP address of anyone in your class, even if they’re
connected to a different router!
you’ve sent your request for the IP Address, the DNS will respond with the
hostname and the IP address (shown on the left)
After the DNS has returned
your partner’s IP, you may contact them directly by typing the IP address into
the “To” field, entering a message, and then pressing “send.”
