香港第一线集团是香港的一个IDC服务商
在这里以香港第一线集团网站（www.dyxnet.com）为例说明其所属的数据中心是几线BGP接入
1、首先通过traceroute命令查询网站IP对应的AS号
traceroute -A www.dyxnet.com
我们得到香港第一线集团网站IP地址是202.134.93.74，其所属的数据中心AS号是9584，对应的出口IP地址是202.134.94.89
今天很奇怪的是只有在广东的服务器上面才能traceroute出某个ip地址的结果，可能全国大网做了什么限制traceroute
2、通过whois命令查询香港第一线AS号的出口IP归属
whois 202.134.94.89
可以看到202.134.64.0 - 202.134.95.255 这一段ip地址都是属于香港第一线集团的，其网站IP地址202.134.93.74正是在这一段IP地址内。
3、通过whois命令查询香港第一线集团数据中心是几线BGP接入
whois AS9584
在这里可以看到，香港第一线集团的AS号9584和AS4635、AS4058、AS4637建立了BGP连接，是一个三线BGP。
我们还可以继续查这3个AS对应的相关信息
AS4635是来自香港中文大学的一个互联网路由出口
AS4058就更强大了，和几十个AS自治系统互联！
