      • Dear SIG members

        The Problem statement "Registration of detailed assignment information
        in whois DB" has been assigned a Policy Proposal number following the
        submission of a new version sent to the Policy SIG for consideration.

        The proposal, "prop-115-v001: Registration of detailed assignment
        information in whois DB" now includes an objective and proposed solution.

        Information about this and earlier versions is available from:

        prop-115-v001: Registration of detailed assignment information in
                       whois DB

        1. Problem statement

            Recently, there are some cases need to get IP address assignment
            information in more detail to specify user IP address.

            With out this information, operators cannot filter out specific
            address range, and it might lead to 'over-filter' (i.e. filtering
            whole ISP's address range).

            For example:

            1) 'Port' range information in IPv4

                ISPs are using 'CGN' or other kinds of IPv4 address sharing
                technology with assignment of IP address and specified port
                range to their users.

                In this case, port information is necessary to specify one user.

                ex) 1-256 is for HomeA
           257-511 is for HomeB

                or 1-65536 is shared address of ISP-X
                minimum size is /32

            2) address assignment size information in IPv6

               The IPv6 address assignment size may be different from ISP to
               ISP, and address ranges in one ISP. Address assignment prefix
               size will be necessary.

               ex) 2001:db8:1::0/56 is for HomeA
                   2001:db8:1:1::0/48 is for HomeB

                   or 2001:db8:1::/36's minimum size is /56

        2. Objective of policy change

            Lots of operators look a record when harmful behavior coming to
            their network to identify its IP address confirming it can be
            filtered or not.

            The goal is providing more specific information to support these

        3. Situation in other regions

            No same regulation/discussion can be seen in other regions.

        4. Proposed policy solution

            Provide accurate filtering information generated from whois DB.

            For IPv4, propose to add 'port range' information to IP address

            For IPv6, propose to provide 'assignment prefix size' information
            for specific IPv6 address.

        5. Advantages / Disadvantages


         - operators can set filtering by IP address based on correct assignment
           information base.

         - users who share same address space can be avoid to be including bulk


         - registration rule will move to more strict manner.

         - strict watch and control in registration of database records.

         - additional record or option will be considered.

         - privilege for withdrawing detailed information will be set for these

        6. Impact on APNIC

            This might be beyond the scope of using whois DB.

        7. Other Consideration

            For the security reason, this detailed records may be able to see
            only by operators.(some kind of user control/privilege setting is

            For hosting services, /32 in IPv4 and /128 in IPv6 registration
            should be discussed based on its operability and possibility. But a
            harmful activities to filter by IP addresses are coming from hosting
            services as well. Here it seemed to be some demands.
