Re: [Hipsec] Selection of LSI address block

in the OpenHIP software we have a macro IN_LOOP() to check if an IPv4
address is equal to 
(INADDR_LOOPBACK >> IN_CLASSA_NSHIFT), i.e. if the top bits equal 127
(see /usr/include/netinet/in.h on Linux)

I wonder if other applications use similar techniques to check for
loopback addresses? Using 127.100.0.0/16 would be problematic in that
case.
