- MANAGEMENT BULLETIN
-
- 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.
