通常不会这样做，但看起来 bi NIC 输入了 TLD 本身的域记录。当您对该 IP 执行 PTR（反向 DNS）记录搜索时，您会得到以下结果：
Non-authoritative answer:
205.8.2.196.in-addr.arpa name = ns.nic.bi.
通常 TLD（顶级域）现在应该附加 A 记录。
bi 的 DNS 记录如下：
;; QUESTION SECTION:
;bi. IN ANY
;; ANSWER SECTION:
bi. 38400 IN TXT "Check the website http://www.nic.bi"
bi. 38400 IN TXT "Top-level Domain of the Republic of Burundi"
bi. 38400 IN TXT "NIC Burundi"
bi. 38400 IN TXT "Top-level Domain of .bi"
bi. 38400 IN A 196.2.8.205
bi. 38400 IN SOA ns.nic.bi. registrar.nic.bi. 2011070201 21600 3600
It's not normally done, but it looks like the bi NIC entered a domain record for the TLD itself. When you do a PTR (Reverse DNS) record search on that IP you get the following:
Non-authoritative answer:
205.8.2.196.in-addr.arpa name = ns.nic.bi.
Normally TLD (Top-level domains) should now have A records attached to them.
The DNS records for bi are as follows:

Once upon a time, in an arpanet far away, Mockapetris wrote the initial specification for DNS. As written, absolute names ended with ., and relative names did not.
Well, that idea lasted about 25 seconds in the face of actual human beings typing in names. Instead, unqualified names are relative -- unless they happen to be tlds. In which case they aren't.

The DNS records for bi are as follows:
域名由用点分隔的一个或多个部分组成。名称
bi只有一个部分，因此不需要任何点。域名可能有与其关联的A（地址）记录。看起来像
bi可以，但例如uk则不然。A domain name is made up of one or more parts separated by dots. The name
bihas only one part, and therefore does not need any dots.Domain names may have an A (Address) record associated with them. It looks like
bidoes, but for exampleukdoes not.这是布隆迪的顶级代码。它与 www.bi 是同一网站。
It's the top level code for Burundi. It is the same site as www.bi.
很久以前，在遥远的阿帕网中，Mockapetris 编写了 DNS 的初始规范。正如所写的，绝对名称以
.结尾，而相对名称则没有。好吧，面对真人输入名字，这个想法持续了大约 25 秒。相反，非限定名称是相对的——除非它们恰好是顶级域名。在这种情况下，他们就不是。
