Last night we uploaded a new user interface (UI) for the Minerazzi Multiple Whois Miner (http://www.minerazzi.com/labs/whois.php).
Added support to:
1. generic third-level domains (gTLDs).
2. country-code TLDs.
3. subdomain TLDs.
As we keep improving and adding new TLDs and whois servers to its index, we expect this to become a destination for our regular users.
The tool was designed in such a way that even support to the upcoming dotBrand Revolution is possible.
