"Registrar WHOIS Server" not being used

[lbschenkel]

$ whois --version
Version 5.5.6.

Maybe I'm missing something, but when I do something like this:

$ whois domain.org

I was expecting whois to make a second query against Registrar WHOIS Server, which is whois.domain.com in this case. This happens correctly for some domains (example: namesilo.net) but not others, like in the above case.

I can see that the code is supposed to be following those, like in here:

whois/whois.c

Line 903 in b7cfb4e

if (state == 1 && strneq(buf, "Registrar WHOIS Server:", 23)) {

and I don't quite get why that works for some domains and not others.

[rfc1036]

My understanding is that .org is managed as a thick registry, so recursion should not be needed. I am not sure if something changed recently.

I'm also searching for a solution for this issue as i don't get all the info with the whois client

[rfc1036]

And now the registrar server returns an http URL as a referral. Are you able to find referrals not to HTTP(S)?
