The ARPANET Official Network Host Table, as outlined in RFC 608, no longer suits the needs of the DoD community, nor does it follow a format suitable for internetting. This paper specifies a new host table format applicable to both ARPANET and Internet needs.

DoD INTERNET HOST TABLE SPECIFICATION
The ARPANET Official Network Host Table, as outlined in RFC 608, no
longer suits the needs of the DoD community, nor does it follow a
format suitable for internetting. This paper specifies a new host
table format applicable to both ARPANET and Internet needs.
In addition to host name to host address translation and selected
protocol information, we have also included network and gateway name
to address correspondence, and host operating system information.
This Host Table is utilized by the DoD Host Name Server maintained by
the ARPANET Network Information Center (NIC) on behalf of the Defense
Communications Agency (DCA) (RFC 811). It obsoletes the host table
described in RFC 608.
LOCATION OF THE STANDARD DoD ONLINE HOST TABLE

is online in the file

FTP server, logging in as user=ANONYMOUS, password=GUEST, and doing a

1. A "name" (Net, Host, Gateway, or Domain name) is a text string up
to 24 characters drawn from the alphabet (A-Z), digits (0-9), and the
minus sign (-) and period (.). No blank or space characters are
permitted as part of a name. No distinction is made between upper
and lower case. The first character must be a letter. The last
character must not be a minus sign or period. A host which serves as
a GATEWAY should have "-GATEWAY" or "-GW" as part of its name. A
host which is a TIP or a TAC should have "-TIP" or "-TAC" as part of
its host name, if it is an ARPANET or DoD host.
2. Internet Addresses are 32-bit addresses (RFC 796). In the host
table described herein each address is represented by four decimal
numbers separated by a period. Each decimal number represents 1
