...you can find that:
#These addresses have been further assigned to Brazilian users. #Contact information can be found at the WHOIS server located #at whois.registro.br and at http://whois.nic.br
Well, if you could speak Portuguese you would immediately see that they shuffled the website and the page you want is at http://registro.br/cgi-bin/nicbr/whois And if you don't speak Portuguese, how are you going to communicate with a small Brazilian ISP in the first place? Also, you have identified an error at LACNIC and you probably should tell them so that they can correct their whois server. LACNIC does have English language capability. --Michael Dillon P.S. The whole concept of looking up an abuse contact in a whois database is completely broken and needs to be scrapped. It simply does not scale. We need some hierarchy here as in many other areas of the network.
