Something strange seems to be going on, as EuroDNS’ WHOIS gave me this:
The Israel Internet Association’s WHOIS however returned them correctly:
I can’t seem to find if your registrar enforces a nameserver check as KangJL described, you can try asking them about it. However, since two WHOIS searches failed, and if the nameserver update was recent, it’s entirely possible the record hasn’t been updated everywhere yet:
My best guess is that something is wrong on the domain registrars side. Because while WHOIS records appear to be updated, the actual nameservers appear to be on their default settings. Please try contacting your domain registrar (The place you bought the domain from) for assistance.
