A new Request for Comments is now available from the Network Information Center in the online library at NIC.DDN.MIL. RFC 1219: Title: On the Assignment of Subnet Numbers Author: P. Tsuchiya Mailbox: tsuchiya@thumper.bellcore.com Pages: 13 Characters: 30,609 Updates/Obsoletes: none pathname: RFC:RFC1219.TXT This memo suggests a new procedure for assigning subnet numbers. Use of this assignment technique within a network would be a purely local matter, and would not effect other networks. Therefore, the use of these procedures is entirely discretionary. This memo provides information for the Internet community. It does not specify an Internet standard. Distribution of this memo is unlimited. RFCs can be obtained via FTP from NIC.DDN.MIL, NIS.NSF.NET, or NISC.JVNC.NET. RFCs can be obtained via FTP from NIC.DDN.MIL, with the pathname RFC:RFCnnnn.TXT (where "nnnn" refers to the number of the RFC). Login with FTP, username "anonymous" and password "guest". The NIC also provides an automatic mail service for those sites which cannot use FTP. Address the request to SERVICE@NIC.DDN.MIL and in the subject field of the message indicate the RFC number, as in "Subject: RFC nnnn". To obtain RFCs from NIS.NSF.NET via FTP, login with username "anonymous" and password "guest"; then connect to the RFC directory ("cd RFC"). The file name is of the form RFCnnnn.TXT-1 (where "nnnn" refers to the number of the RFC). The NIS also provides an automatic mail service for those sites which cannot use FTP. Address the request to NIS-INFO@NIS.NSF.NET and leave the subject field of the message blank. The first line of the text of the message must be "SEND RFCnnnn.TXT-1", where nnnn is replaced by the RFC number. RFCs can also be obtained via FTP from NISC.JVNC.NET, with the pathname rfc/RFCnnnn.TXT.v.Z (where "nnnn" refers to the number of the RFC and "v" refers to the version number of the RFC). There are a number of RFCs available in postscript format. Those RFCs have modifiers of .PS instead of .TXT. Login with FTP, username "anonymous" and your e-mail address as your password. JvNCnet also provides a mail service for those sites which cannot use FTP. Address the request to NISC@JVNC.NET and in the subject field of the message indicate the RFC number, as in "Subject: RFC nnnn". Requests for special distribution should be addressed to either the author of the RFC in question, or to NIC@NIC.DDN.MIL. Unless specifically noted otherwise on the RFC itself, all RFCs are for unlimited distribution. Submissions for Requests for Comments should be sent to POSTEL@ISI.EDU. Please consult RFC 1111, "Instructions to RFC Authors", for further information. Requests to be added to or deleted from this distribution list should be sent to RFC-REQUEST@NIC.DDN.MIL. Joyce K.
