例子
Names and addresses in general
An address is how you get to an endpoint
Typically, hierarchical (for scaling):
950 Milton Street, Brisbane City, QLD 4064

A “name” is how an endpoint is referenced
Typically, no structurally significant hierarchy
“David”, “Tokyo”, “”
Purpose of naming
Addresses are used to locate objects
Names are easier to remember than numbers
You would like to get to the address or other objects using a name
DNS provides a mapping from names to resources of several types
Naming History
1970’s
maintained by the SRI-NIC
pulled from a single machine
Problems
traffic and load
Name collisions
Consistency
DNS created in 1983 by Paul Mockapetris (RFCs 1034 and 1035), modified, updated, and enhanced by a myriad of subsequent RFCs
2. IP地址和主机名(域名)的转换方法
Host表(/etc/hosts文件)
存放了主机名和IP地址的映射表
在大型网络中建立Host表几乎不可能
NIS
将所有的Host数据保存在中央主机上,由中央主机将所需的数据分配给所有的服务器
只适用于中小型网络
DNS
上的域名和IP地址之间的映射
主机信息的中心数据库
hosts文件
文件/etc/hosts的格式
IP地址主机名/域名
例子
center.
news.
注意:hosts文件中的IP地址和域名之间的映射关系,只能供本机使用,而不能被其他机器访问
DNS
A lookup mechanism for translating objects into other objects
A globally distributed, loosely coherent, scalable, reliable, dynamic prised of ponents
A “name space”
Servers making that name space available
Resolvers (clients) which query the servers about the name space
DNS Features: Global Distribution
Data is maintained locally, but retrievable globally
No puter has all DNS data
DNS lookups can be performed by any device
Remote DNS data is locally cachable to improve performance
