Yes. Given the data you've provided, I retract my first hunch: it seems
your student is seeing a different host:
- either DNS resolves to a different IP address -- then you'd see
different IP addresses for your server as viewed from your student's
workstation wrt the "rest of the world
- or routing sends your student to a different host (claiming the
same IP address, that stinks ;-)
Traceroute might help in the second case. Besides, you wouldn't see your
student's access attempts in your server logs -- after all, he's knocking
at another door.

Dear Linuxers,
I just want to close this issue by thanking everyone who chipped in with help and attempts to solve the problem
Unfortunately the mistery will go on, because my student solve the problem by changing his ISP server.
He told that the problem was solved immediately, as we predict and tested (via mobile and the neighbor's internet).
So, I cannot run any more tests, and I'll stay curious about what really happened.
My bet: the "homebrew ISP" has a DNS problem.
Thanks.
