As
http://www.freebsd.org/cgi/man.cgi?query=inet_aton&apropos=0&sektion=0&manpath=FreeBSD+10.0-RELEASE&arch=default&format=html,
on sees the text:
When a two part address is supplied, the last part is interpreted as a
24-bit quantity and placed in the right most three bytes of the network
address. This makes the two part address format convenient for specify-
ing Class A network addresses as ``net.host''.
In the second line, there should I believe be the substitution:
s/network$/host$/.
I have no FreeBSD system to test, but have tested on OpenBSD and Linux.
Furthermore, the change makes sense when one reads the surrounding text.
I see the same text in the OpenBSD page, and also the NetBSD page. How does
this work -- should I submit bugs for each of those systems, or do communicate
such problems to one another?
Thanks,
Michael Kerrisk

Test code:
#define _BSD_SOURCE
#include <arpa/inet.h>
#include <stdio.h>
#include <stdlib.h>
static void
printBytes(in_addr_t a)
{
printf("%d", (a >> 24) & 0xff);
printf(".");
printf("%d", (a >> 16) & 0xff);
printf(".");
printf("%d", (a >> 8) & 0xff);
printf(".");
printf("%d", (a & 0xff));
} /* printBytes */
int
main(int argc, char *argv[])
{
struct in_addr addr;
if (argc != 2) {
fprintf(stderr, "%s <dotted-address>\n", argv[0]);
exit(EXIT_FAILURE);
}
if (inet_aton(argv[1], &addr) == 0) {
fprintf(stderr, "inet_aton() failed\n");
exit(EXIT_FAILURE);
}
printf("%s\n", inet_ntoa(addr));
struct in_addr n, h;
n.s_addr = inet_netof(addr);
printf("Network number : ");
printBytes(n.s_addr);
printf("\n");
h.s_addr = inet_lnaof(addr);
printf("Local network address: ");
printBytes(h.s_addr);
printf("\n");
addr = inet_makeaddr(n.s_addr, h.s_addr);
printf("Made address: %s\n", inet_ntoa(addr));
exit(EXIT_SUCCESS);
}
