浅淡DNS与whois关系
不引战 仅个人见解
没必抓住不放 各有各见解
本文dns缺省指权威服务器 其它另注
Dns与whios并无实际联系Whois是商业产物 供公众查询所属人
在dns修改域名的ns record 可不在whois表现
域解析过程
本机向public dns查询
public dns向root dns询问nic的ns
Public dns向nic dns问registry domain的ns
registry domain dns反回ip到public dns
Root dns是以ip domain文本格式固定的 搭过public dns的都明白有个root.db 里面正是root dns地址
主根服务器都在资本主义国家手上国内有镜像根 可独立运行
贴dig过程
