Umm, no. That won't work very well at all, as the host then will seem
to be up no matter if it's on fire or whatever happens to it.

A more appropriate method would be to check something else on the host
that the host can (and does) respond to properly. TCP connections to
some random (open) port is usually a fairly decent bet.
