DDNS (Dynamic DNS)
Dynamic Update is a method for adding, replacing or deleting records in a master server by sending it a special form of DNS messages. The format and meaning of these messages is specified in RFC 2136.
自譯：DDNS是一種用來新增、替換或刪除Master DNS server中Resource Record Data的方法…相關內容可見RFC文件冊編號2136
==> 文件冊看這兒RFC2136 <==

The logging statement configures a wide variety of logging options for the name server.
Its channel phrase associates output methods, format options and severity levels with a name that can then be used with the category phrase to select how various classes of messages are logged.

在官方說明文件的第三章中的Tools for use with the name server daemon
有提到rndc這個指令~

The remote name daemon control (rndc) program allows the system administrator to control the operation of a name server.
也就是允許遠端控制DNS Server 啦~

很多東西都有ACLs…但每種東西設定的方法都不一樣~

那DNS的ACLs是做什麼功能吶?

TSIG是做什麼的吶？

Transaction SIGnatures (TSIG) based transaction security in BIND. 啥米…有聽沒有懂～繼續往下看囉

看DNS的Master與Slave架構吧
比較於基本架構…稍微難一些~

Computers communicate with each other using their IP addresses. But for humans, it is simpler to address a computer using its name.
DNS (Domain Name System) is a distributed database system that guarantees unique computer names worldwide.
It provides computers with IP addresses when a user enters a computer name,and vice versa.

簡單來說…就是為了幫助人…記憶網路名稱(host.DomainName)與網路位址(IP Address)用的，反之也成立喔~ >.<
