Whois vs privacy extension

Isn't there a way to reveal name only on request in the whois database ?
Current obfuscation shows name for the ip block. Using privacy extension is less interesing if people can link your id to any generated ip using whois.

Can you elaborate on the exact query/url/whatever you are meaning, there are quite a couple of options there. A "This URL/Query" along with "this is the current output" and "but I would like it this way", would be useful.

The whole point is that whois links an IP/prefix to the responsible person, as far as we know, that is exactly what it does today.
What is the exact problem you are having with it?

I guess his problem is, without a court order, his IPv4 can only be resolved to "Some user of X-telecom" perhaps in Y-city.
But his IPv6 can be resolved to his name by everyone, because he is the responsible person for the IP/prefix.
Someday, when ISP's give the IP/prefix, it probably won't be "whois'able" below the ISP-level, just like IPv4
I don't know if other tunnel brokers give contact informations on IP/prefix in whois.
On native IPv6, will the customer not still have a fixed IP/prefix?
So if I want to track customers to my website, I just need to store the upper 64 bits, then I'll know from which household he comes, never mind which random adress there below?

I hope they handle abuse properly, having ones data published is a deterrent that way as one can get both name and IPv4 address for the IPv6. As such, when somebody is annoying they can nicely take it on with the IPv4 address instead of with the IPv6 connectivity.

Depends on the ISP, but generally yes.

That is an option indeed. The question becomes though, do you have enough storage to store all 64bits ;)
With users being mobile, it won't help much anyway as they change around a lot of prefixes.
Also you the only know that it is the same site, not if it is the same user.

Sorry, I was pushed offline for a week.

Yes, that's the problem. Looking up the /64 block, you can know this is the same person, AND its name have trong probability of being the one revealed by whois identity.
The whois 'obfuscation' should also include name. Identity should be resolvable on request, but not be possible using automated tools :/

If one needs to hide on the Internet, then SixXS is really the wrong place.
Please try Tor or other anonymity such systems if you want to be anonymous.

It would be exactly the same in IPv4 world. If you request IPv4 subnet from your ISP you have rather big chance to be named in appropriate whois DB.
Note that the name in whois DB does not point at user of the address space. It does indicate who have requested it, administers it and so is responsible for it. You may have hundreds or even thousands of actual users using the IPs from within assigned subnet, which you are contact for listed in whois DB.
