897     Postel       Feb 84      Domain Name System Implementation
                                 Schedule

   This memo is a policy statement on the implementation of the Domain
   Style Naming System in the Internet.  This memo is a partial update
   of RFC 881.  The intent of this memo is to detail the schedule for
   the implementation for the Domain Style Naming System.  The names of
   hosts will be changed to domain style names.  Hosts will begin to use
   domain style names on 14-Mar-84, and the use of old style names will
   be completely phased out before 2-May-84.  This applies to both the
   ARPA research hosts and the DDN operational hosts.  This is an
   official policy statement of the ICCB and the DARPA.

   This RFC specifies a draft standard for the ARPA Internet community.
   It describes a resource location protocol for use in the ARPA
   Internet.  It is most useful on networks employing technologies which
   support some method of broadcast addressing, however it may also be
   used on other types of networks.  For maximum benefit, all hosts
   which provide significant resources or services to other hosts on the
   Internet should implement this protocol.  Hosts failing to implement
   the Resource Location Protocol risk being ignored by other hosts
   which are attempting to locate resources on the Internet.

886     Rose         Dec 83      Proposed Standard for Message Header

                                 Messages

   This memo is distributed as an RFC only to make this information
   easily accessible to researchers in the ARPA community.  It does not
   specify an Internet standard.  This RFC defines the standard format
   for interchange of Network News articles among USENET sites.  It
   describes the format for articles themselves, and gives partial
   standards for transmission of news.  The news transmission is not
   entirely standardized in order to give a good deal of flexibility to
   the individual hosts to choose transmission hardware and software,
   whether to batch news and so on.

                                 February 1983

   This survey determines how many hosts are able to respond to TELENET
   connections from a user at a class C site.  This requires, in
   addition to IP and TCP, participation in gateway routing via ICMP and
   handling of Class C addresses.  The list of hosts was taken from RFC
   843, extracting only those hosts which are listed there as accepting
   TELNET connection.  The tests were run on 18-Feb-83.

802     Malis        Nov 81      The ARPANET 1822L Host Access Protocol

   This document proposed two major changes to the current ARPANET host
   access protocol.  The first change will allow hosts to use logical
   addressing (i.e., host addresses that are independent of their
   physical location on the ARPANET) to communicate with each other, and
   the second will allow a host to shorten the amount of time that it
   may be blocked by its IMP after it presents a message to the network
   (currently, the IMP can block further input from a host for up to 15
   seconds).  See RFCs 852 and 851.
