what is URL/ud/14916?

[dhenry]

According to my firewall logs (PIX515) for the past few days I have many of the computers on my campus accessing a few different servers on the internet with the site being /ud/14916. Here are a few examples
66.147.182.45/ud/14916
209.201.118.197/ud/14916
63.210.132.195/ud/14916
If I go to those computers, the users are doing various things, not always Internet related. I have tried to open up the sites in IE but I always get page not found. Has anyone seen this before and/or knows what this is? It has me stumped.

Thanks.

What i can tell you: The first Adress belongs to Digital-Island.

Only the ports 80 - 83 are open to the Internet. It seems that is a regular PC. perhaps somebody of the students had started a Chat program osr something like that.

hnd:
There are many more sites with the same /ud/14916 that are trying to be accessed. Some of the computers doing this are instructor computers and may continue even if the computer is rebooted.

Looking at the logs this morning, these internet requests make up about 50% of all requests.
