Dear Walter Roberson!

Exactly.

The question was (analogous): **How** do I check the availability of a certain internet service in Matlab?
We cannot clear the question **what** Jaime Zamora wants to do.

Quantum-cryptography would not help for this reason, usually. 

Considering evil DNS administrators would not help, either.

Theories about human perception would not help, either (I have to admit).

"java.net.URL" recommended by Scott can help (but not under 100% of all imaginable and not-imaginable situations).

"URLREAD" might help also (but not under 100%...).

Good luck, Jan
