Hmm, that page is working fine for me... OK, here you go, excerpt from that page: : Traditional BSD kernels have only supported mapping IP addresses to Ethernet : 6-byte MAC addresses (and the FDDI and Token-Ring lookalikes). : However, when dealing with other types of addresses like ARCnet, AX25 packet : radio, etc. with a different length, more general aspects of the ARP mapping : have to be implemented. This paper reports on the one-to-N mapping developed : for NetBSD. : : Old BSD networking up to and including 4.4BSD-lite has only supported IP version : 4 over Ethernet. All modern operating systems based on 4.4BSD-lite have inherited : this limitation. The exception are link types that use the same 6-byte addressing : as Ethernet (e.g., FDDI). : ... Reading the whole page is still necessary, it provides much more detail about the changes. -- Andre To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
