Internet Society Requests For Comment (RFCs)
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.

Domain Name System Implementation Schedule
Status of this Memo
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. This is an official policy statement of the ICCB and the DARPA.
The intent of this memo is to detail the schedule for the implementation for the Domain Style Naming System. The explanation of how this system works is to be found in the references.
The Current Situation
Hosts in the ARPA research and DDN operational communities are currently assigned names in a flat or global name space of character strings. There are some limits on these names. They must start with a letter, end with a letter or digit and have only letters or digits or hyphen as interior characters. Case is not significant.
For example: USC-ISIF
Every host in the Internet is expected to have a way of translating the name of any other host into its Internet address.
By and large, the name to address translation is done by looking up the information in a table of all hosts.
The maintenance of this table is centralized at the Network Information Center (NIC). Each host is expected to obtain a current copy of the table on a timely basis.
Interface to the World
A great deal of mail moves between the Internet and other "systems" that somehow transport mail among computers. This is currently done by hiding some sort of "other-system" addressing information in the local-part of the mail address and using a mail-relay host in the host-part of the mailbox.

The Future Situation
Because of the growth of the Internet, structured names (or domain style names) will be used. Each element of the structured name will be a character string (with the same constraints that previously applied to the simple names).
For example: F.ISI.USC.ARPA
Every host in the Internet will be expected to have a way of translating the name of any other host into its Internet address.
By and large, the name to address translation will be done by interacting with a service. There will be a number of servers that each hold a portion of the name to address information.
The maintenance of the translation data will be subdivided and distributed.
There are several stages of implementation for the servers and several levels of development for use of the domain style names.
First, there is the simple substitution of the domain style names for the current host names, and the subdivision of these into several domains. At this stage all domain style names directly translate to host addresses and all domain style names have two components.
For example: USC-ISIF.ARPA or USC-ISIA.DDN
and: Postel@USC-ISIF.ARPA or Kahn@USC-ISIA.DDN
