|
|
The DDN MANAGEMENT BULLETIN is distributed online by the DDN Network
|
|
Information Center under DCA contract as a means of communicating
|
|
official policy, procedures and other information of concern to
|
|
management personnel at DDN facilities. Back issues may be read
|
|
through the TACNEWS server ("@n" command at the TAC) or may be
|
|
obtained by FTP (or Kermit) from the SRI-NIC host [26.0.0.73 or
|
|
10.0.0.51] using login="anonymous" and password="guest". The pathname
|
|
for bulletins is DDN-NEWS:DDN-MGT-BULLETIN-nn.TXT (where "nn" is the
|
|
bulletin number).

PHASE 1 OF THE DOMAIN NAME IMPLEMENTATION
|
|
|
|
The DDN Network Information Center (NIC) is directed to remove all
|
|
nondomain-style host names and nicknames from the Official DoD Host
|
|
Table, NETINFO:HOSTS.TXT, by 31 March 1987. After that time, names
|
|
which do not conform to domain-style naming conventions, i.e. do not
|
|
have ".domain" extensions, will not be allowed in either the Official
|
|
DoD Host Table or the domain name servers.
|
|
|
|
Nicknames, or aliases, will not be permitted in either the servers or
|
|
the Official Host Table unless authorized. Network mailers are
|
|
required to use primary host names and to accept host names containing
|
|
dots (.), as specified in the DDN mail protocols RFC 821 (MILSTD-1781)
|
|
and RFC 822. If mailers are not now adhering to these protocol
|
|
requirements, they may experience mail delivery problems when the
|
|
nondomain-style names are discontinued. Users sending electronic mail
|
|
should use primary host names in all mail destinations and sources.
|
|
If nicknames are used, problems may arise in mail delivery.
|
|
|
|
The NIC will notify Host Administrators as to which names or nicknames
|
|
do not now conform. Host Administrators may change nonconforming data
|
|
by the usual procedure via Network Change Requests (NCRs) and Network
|
|
Change Directives (NCDs), if they wish, before the 31 March 1987
|
|
deadline.
|
|
|
|
Host Administrators anticipating problems with this plan should notify
|
|
DCA Code B652 (DCAB652@DDN1.ARPA), or via AUTODIN message, and the NIC
|
|
Hostmaster (HOSTMASTER@SRI-NIC.ARPA) no later than 2 weeks prior to
|
|
the scheduled cutover.
|
|
|
|
In March of 1984, the DDN began the transition to domain-style names
|
|
with the issuance of DDN Management Bulletin 22. In that bulletin,
|
|
all hosts were required to change their primary host names to contain
|
|
".domain" extensions in accordance with RFC 897. At the same time,
|
|
all of the old-style names (without the ".domain" extensions) were
|
|
automatically declared to be nicknames in the Official Host Table,
|
|
NETINFO:HOSTS.TXT. This use of old-style nicknames was allowed on an
|
|
interim basis to make the transition to domain-style naming easier.
|
|
Almost three years have passed, and this transition period must now
|
|
come to a close.
|
|
|
|
The transition to naming domains has progressed to the point where
|
|
there are many domain name servers implemented and running. In order
|
|
to maintain interoperability between hosts on the DDN using the host
|
|
table and hosts using the domain name servers, all hosts must be able
|
|
to recognize domain-style names. It is imperative that all transition
|
|
names and nicknames be upgraded to domain-style names or be removed
|
|
from NETINFO:HOSTS.TXT so that naming is consistent and so that all
|
|
use of names adheres to the specification for domain names adopted in
|
|
1984.
