TC (Truncated) Bit In query messages, the Truncated bit MUST be zero on transmission, and MUST be ignored on reception. In response messages, if the message does not contain all the data the requester was looking for, the requester SHOULD open a TCP connection to the responder and repeat the query. How do you open a TCP connection to a multicast address? If it means the requester should open a TCP connection unicast, how does it find the address? -- From owner-zeroconf@merit.edu Sun Jun 2 20:47:59 2002 Received: from trapdoor.merit.edu (postfix@trapdoor.merit.edu [198.108.1.26]) by ietf.org (8.9.1a/8.9.1a) with ESMTP id UAA21261 for ; Sun, 2 Jun 2002 20:47:59 -0400 (EDT) Received: by trapdoor.merit.edu (Postfix) id DDDF691225; Sun, 2 Jun 2002 20:48:15 -0400 (EDT) Delivered-To: zeroconf-outgoing@trapdoor.merit.edu Received: by trapdoor.merit.edu (Postfix, from userid 56) id ABCBB9122C; Sun, 2 Jun 2002 20:48:15 -0400 (EDT) Delivered-To: zeroconf@trapdoor.merit.edu Received: from segue.merit.edu (segue.merit.edu [198.108.1.41]) by trapdoor.merit.edu (Postfix) with ESMTP id 9F8AF91225 for ; Sun, 2 Jun 2002 20:48:14 -0400 (EDT) Received: by segue.merit.edu (Postfix) id CD4775DE14; Sun, 2 Jun 2002 20:48:08 -0400 (EDT) Delivered-To: zeroconf@merit.edu Received: from motgate3.mot.com (motgate3.mot.com [144.189.100.103]) by segue.merit.edu (Postfix) with ESMTP id 6F0505DE05 for ; Sun, 2 Jun 2002 20:48:08 -0400 (EDT) Received: [from pobox4.mot.com (pobox4.mot.com [10.64.251.243]) by motgate3.mot.com (motgate3 2.1) with ESMTP id RAA22457; Sun, 2 Jun 2002 17:47:57 -0700 (MST)] Received: [from homer.arc.corp.mot.com (homer.arc.corp.mot.com [10.238.80.38]) by pobox4.mot.com (MOT-pobox4 2.0) with ESMTP id RAA05969; Sun, 2 Jun 2002 17:48:10 -0700 (MST)] Received: from motorola.com (aidanw.arc.corp.mot.com [10.238.80.63]) by homer.arc.corp.mot.com (8.12.2/8.12.2) with ESMTP id g530m8jd006174; Mon, 3 Jun 2002 10:48:08 +1000 (EST) Message-ID: <3CFABCC8.A4F4B999@motorola.com> Date: Mon, 03 Jun 2002 10:48:08 +1000 From: Aidan Williams Reply-To: Aidan_Williams-A15677@email.mot.com Organization: aidan@arc.corp.mot.com X-Mailer: Mozilla 4.76 [en] (Windows NT 5.0; U) X-Accept-Language: en MIME-Version: 1.0 To: Michael Rutman Cc: zeroconf@merit.edu Subject: Re: Truncate bit References: Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-zeroconf@merit.edu Precedence: bulk Content-Transfer-Encoding: 7bit Michael Rutman wrote: > > Sorry if this has already been addressed, but I was reading > draft-cheshire-dnsext-multicast and came across this. > > 17.5.
