Don't ever catch a bare Exception class. Make it more specific to the
particular problem you're trying to suppress.
In particular, your previous problem with the utf-8 decoding will also
be caught by the Exception class, so it'll get all lumped together as
"Reverse DNS Failed".

Since you've not made any progress with all the other suggestions, how
about if you decompose this line into several, and see just which one is
failing? Maybe that'll tell you what's going on. In general,
suppressing an exception without knowing why it's firing is a huge mistake.
The line started as:
> host = socket.gethostbyaddr( os.environ['REMOTE_ADDR'] )[0]
refactor that to:
remadd = os.environ('REMOVE_ADDR')
tuple3 = socket.gethostbyaddr(remadd)
host = tuple3[0]
and see which one throws the exception. Then once you have that,
examine the exact parameters that might be triggering the problem. In
particular, figure out the exact types and values for remadd and tuple3.
print(type(remadd) + " : " + repr(remadd))
Of course, print itself won't work too well in a CGI environment. But
you must have solved that problem by now, either using log files or
running the program excerpt in a regular console.
