Ah, okay, thanks for clearing this up :)

But the LuaSocket docs don't say that '*' is the default. In fact, the address
argument is listed as mandatory. That is why I was under the impression
that the address argument is something that will differ from case to case.
But obviously, this is not the case. 90% of the users will probably use
'*' as address then. So it would probably be wise to either make the
address argument optional (with a default fallback to '*') or mention in the
bind docs something like:

"Normally you will want to use '*' as address" 

Just my 2 cents :)
