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) 192.0.2.24/32 1-256 is for HomeA
192.0.2.24/32 257-511 is for HomeB
or 192.0.2.0/24 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
actions.
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
entry.
For IPv6, propose to provide 'assignment prefix size' information
for specific IPv6 address.
5. Advantages / Disadvantages
-----------------------------
Advantages:
- 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
filtering.
Disadvantages:
- 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
records.
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
needed)
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.
