I will state unequivocally that most DHCP clients use a local mail relay. And the local relay will use a "generic" hostname on the email address. Also, the DNS "name" has nothing to do with the host's name. The sites DNS admins will have both forward and reverse (A & PTR) RR's. Also I will state in large shops, they don't hardcode IPs to particular machines. Thus over time a machine has many different IPs. People would not be too happy to see their hostnames change all the time, nor to be the typical "foo-bar-dhcp-134-89" that the assigned IP will resolve to. In a Winloose network, they don't care about matching machine names with DNS hostnames. > This also isn't just pedantry because, as I noted before, specifying > the hostname will currently cause it to override the DHCP hostname > value even if it is specified (as it certainly is on *my* DHCP server :-) Yes, this behavior is ISC's ruled desire. From experience Ted Lemon and Co. knows that most shops don't handout hostnames, and when they do they are long nonsensical ones. -- -- David (obrien@NUXI.com) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
