I have a list of US colleges and I tried to get accurate IP address for all of them. Any place I can search? Thanks.

1. Go to wikipedia
2. Enter the name of the college you want
3. Find the URL for the campus web page
4. Open up a command prompt/terminal
5. Type ping (url from above)

Why are you looking for this? It will be very difficult as there are many providers and they subclass their IP ranges.

Some schools may not have a publically defined block of IP addresses.

You could try contact ARIN link for information to start. It is doubtful there is a concrete list anywhere of all of these though as they change frequently enough that it would require a massive effort to maintain.
