Hi

I am declaring following variables

unsigned long   dstAddr;
unsigned long   gateWay;
unsigned long   mask;

These variables contains ipaddresses in network byte order. So when I am trying to print them using inet_ntoa function for mask variable sometimes it is printing strange values

printf("%s\t%s\t%s\t",inet_ntoa(dstAddr),inet_ntoa(gateWay),inet_ntoa(mask));

  192.168.122.0         0.0.0.0    0.255.255.255

but it should be

  192.168.122.0         0.0.0.0    255.255.255.0

So is this because of inet_ntoa ??
