In class, we discussed domain names and IP addresses.
We mentioned that the URL of the CIS department web server
It's IP address is 220.127.116.11.
Go to the
web site, where you can look up IP addresses of domain names (and vice versa).
There are many things you can do on this web site.
Find the column labeled Hostname Tests and the section labeled
Enter www.sci.brooklyn.cuny.edu in the text field and click on
(don't worry about the dropdown menu to the rigth of the text field --
you can leave that on the default value (A)).
You'll see a results page, which first shows how the domain name
search was perfomed (i.e., through a series of domain name servers),
followed by a table containing the resolution and the IP address of
the host name that you entered, in this case
Click on the IP address and you get even more information!
Your assignment is to look up 3 other sites and report the domain
names and IP addresses.
At least one should be another Brooklyn College web site.
As we discussed in class, the IP address fields are divided into
domain, subnet and host.
Be sure to include in your homework the names and IP addresses of the
three sites you used, and identify the domain, subnet and host for
each IP address.
