The issue is that most whois lookup tools or websites are not sending the correct command the the .NAME whois server (whois.nic.name).
If you connect to
whois.nic.name:43 and issue
?, you get these instructions:
registrar Network Solutions Inc.
det contact 21_CONTACT_NAME-VRSN
ext blocked TEVA.PHARMACEUTICALS.NAME
So the correct command to send to the whois server is to send:
full example.com , where example.com is replaced with the domain name.
If you were to use the
whois command on Linux, then you should execute:
whois -h whois.nic.name 'full example.com'
I have taken this into consideration when building my whois lookup tool at https://gwhois.org/ .
