This document describes the objects necessary to include information about IP networks and IP numbers in the X.500 Directory. It extends the work "Charting networks in the X.500 Directory"  where a general framework is presented for representing networks in the Directory by applying it to IP networks. This memo defines an Experimental Protocol for the Internet community.

Representing IP Information in the X.500 Directory
Status of this Memo
This memo defines an Experimental Protocol for the Internet community. This memo does not specify an Internet standard of any kind. Discussion and suggestions for improvement are requested. Distribution of this memo is unlimited.
This document describes the objects necessary to include information about IP networks and IP numbers in the X.500 Directory. It extends the work "Charting networks in the X.500 Directory"  where a general framework is presented for representing networks in the Directory by applying it to IP networks. This application of the Directory is intended to support the work of IP network assigning authorities, NICs, as well as other applications looking for a mapping of IP numbers to data of related networks. Furthermore, Autonomous Systems and related routing policy information can be represented in the Directory along with their relationship to networks and organizations.

Information related to the Internet Network Infrastructure is created and stored by a number of different organizations, such as the Internet Assigned Numbers Authority (IANA), Internet Registry (IR), Network Information Centers (NICs), and the NSFNET Network Operations Center (NOC). This information is generally "mastered" (stored and maintained) by these organizations on a centralized basis, i.e., there is a single place to look for a definitive list of entries for these categories. This has worked well in the past but given the tremendous growth of the Internet and its number of users and networks, it is essential that a distributed schema be used.
The X.500 Directory offers the appropriate technology for implementing this distributed method of managing network infrastructure information.
The following goals are addressed in this document:
o Provision of IP specific images of network elements o Mapping from Network Number to network, owner, provider etc. o Support of delegation of IP address blocks o Storage of high-level routing policies and AS information o Support of "classless" network...
