ip.7: INADDR_* values cannot be assigned directly to 's_addr'
According to The Open Group Base Specifications Issue 7, RATIONALE
section of
http://pubs.opengroup.org/onlinepubs/
9699919799/ basedefs/netinet_in.h.html
some INADDR_* values must be converted using htonl().
INADDR_ANY and INADDR_BROADCAST are byte-order-neutral so they do
not require htonl(), however I only comment this fact in NOTES.
On the text I recommend to use htonl(), "even if for some subset
it's not necessary".
