These are the addresses that are reserved by standard. Others, as in Dale's message, are reserved by fiat! For example, HP has grabbed, without authorization, a bunch of IANA "experimental" addresses for its JetDirect printers and print servers. No one gave them the addresses; their equipment JUST TAKES THEM. If you let packets for them through your firewall, folks may be able to commandeer your printers. There really should be a good list of addresses that are reserved not only by RFC1918 but also by "land grabs." --Brett To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
