Hi Francesco,

it's called "Wildcard adressing for TCP/IP connections".
It allows the database server on a machine with more than
one network interface cards to accept connections from
clients on each network interface card (with the same port
number). The wildcard in the sqlhosts file is relevant only
for the server. A client ignores the wildcard.

I think a better description of this (than in the old manual
where you found the picture) is in the current "Informix
Administrator's Guide" -> "Chapter 3: Client/server
communications" -> "The sqlhosts information" ->
"Alternatives for TCP/IP connections" -> "Wildcard
addressing for TCP/IP connections".
Or look at:
