Thanks. The default value of the variable may also be an OS default.

The "host_name" field of the procdesc structure is a string pointer, so the string can resolve to an IPv4 or IPv6 address. And as it says in the document, on BProc systems, "host_name" is a BProc node number so the string is also open to interpretations other than just IP address.

Our emails crossed in the ether, but thankfully your reply supports the same conclusion I came to.  :-)
