[sig-db]a proposal for whois db query
Dear all guru :
I am Jeng-jr Li from TTN , Taiwan Telecommunication Network Services .
Here is a rough idea about the whois query working mechanism.
Please post any issue or question regarding this proposal.
Deeply appreciate any feedback/comment.
Cheers

A Proposal for Whois DB Query
--------------------------------------
Introduction:
-----------------
Maintaining whois infomation is not an easy task for ISP or LIR.
If there is already infomation existing in ISP, how about displaying the
whois query
directly from ISP / LIR.
Summary of the current problem:
------------------------------------
1. Real Time Update:
Some ISPs are hard to update the whois data whenever an ip assignment
changes.
Also it's not realtime to batch update for ISP/LIR holding large ip blocks.
This is a chain reaction of another issue , the accuracy of whois
infomation.
2. Man-hour , Man-power Issue
NIC provides webs for LIR to update whois data , however it needs man-hour
and man-power to process the data not suitable for LIR holding large ip
blocks.
Situation in other RIRs:
-------------------------
Details of proposal:
------------------------
Suppose ip address is the requested info.
When a whois client query at a NIC's whois server , whois server will
know that the requested info can be resolved from the LIR's server.
1. The whois server can find the LIR's DNS Server from that ip address's
reverse zone record.
2. LIR's DNS server can response whois's query , otherwise back to the
conventional whois working model .
3. ISP/LIR's DNS server selecting fields from local DB , then feed back to
whois server .
Advantages and disadvantages of adopting the proposal:
-----------------------------------------------------------
Pros :
The current whois protocol do NOT need to change.
This proposed process can start from a local area , thus only impact on one
NIR and the volunteer LIR.
Whois data no longer to update for volunteer LIR.
Cons:
NIR have to prepare the additional programs.
Volunteer LIR also have to prepare the additional programs on it's DNS
server.
ps: sample programs for reference are provided
Effect on APNIC members:
--------------------------------
If the querying model accepted between APNIC and it's members , members will
not to update their ip block's infomation.
Effect on NIRs:
-------------------
NIR have to prepare the additional programs on it's whois server.
