I can't find anything that defines whether you should use 127/8 or just 127.0.0.1. The include/in.h for Linux 2.4 seems to do both, in a way: /* Network number for local host loopback. */ #define IN_LOOPBACKNET 127 /* Address to loopback in software to local host. */ #define INADDR_LOOPBACK 0x7f000001 /* 127.0.0.1 */ #define IN_LOOPBACK(a) ((((long int) (a)) & 0xff000000) == 0x7f000000) -- Juha To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
