X-Mailer: Mozilla 4.6 [en] (Win98; U) X-Accept-Language: en MIME-Version: 1.0 To: questions@freebsd.org Subject: 172.16.0.0 private net question Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 7bit Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG This isn't entirely FreeBSD related but I figure this would be one of the few good places to ask. Is the 172.16.0.0 private network range 172.16.0.0 to 172.31.255.255, or 172.0.0.0 to 172.16.255.255? The netmask is 255.240.0.0, a 12-bit mask. So it makes sense, mathematically, to me, at least, that the IP range would be 172.0 to 172.16. But RFC1918 says it's 172.16 to 172.31. Does the 172.16 net just have the 12th bit always on or something? To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
