反向DNS服务器.in-addr.arpa中的"in"是什么单词的缩写?
我百度和google都查过了找不到答案，也许是搜索方法欠佳。
我猜要么是Internet要么是inverse的意思。虽然这个问题不是很有价值不过不搞清楚老觉得不舒服

是
index
的意思
引自 RFC1033 Page 9
In order to do the reverse translation easily, a domain was created
that uses hosts' addresses as part of a name that then points to the
data for that host. In this way, there is now an 'index' to hosts'
RRs based on their address. This address mapping domain is called
IN-ADDR.ARPA. Within that domain are subdomains for each network,
based on network number. Also, for consistency and natural
groupings, the 4 octets of a host number are reversed.
