一位客户说他们想在我们这里停放一个域名。理论上，他们应该已经注册了该域名。但是当我使用 查找时whois，我得到了以下信息：
jcastro@localhost:~$ whois notactuallythedomaininquestion.br
% Copyright (c) Nic.br
% The use of the data below is only permitted as described in
% full by the terms of use at https://registro.br/termo/en.html ,
% being prohibited its distribution, commercialization or
% reproduction, in particular, to use it for advertising or
% any similar purpose.
% 2017-11-07 09:26:29 (BRST -02:00)
% blocked_word: CG
% Security and mail abuse issues should also be addressed to
% cert.br, http://www.cert.br/ , respectivelly to [email protected]
% and [email protected]
%
% whois.registro.br accepts only direct match queries. Types
% of queries are: domain (.br), registrant (tax ID), ticket,
% provider, contact handle (ID), CIDR block, IP and ASN.
这是什么意思？一个真正不存在的域名不会给我那一blocked_word行，而是给出：
jcastro@localhost:~$ whois randomwordsalad.br
.
.
.
% No match for randomwordsalad.br
.
.
.
答案1
两者的区别在于，WHOIS 输出中显示“blocked word”的名称无法注册，而输出中显示“no match”的名称可以注册，尽管此时尚未注册。
