1、前言：商家技术力和效率实在是让人啧啧称奇。还好配置还算厚道价格还算公道。
2、买！本次机型为1C/1G/20G/500G@100Mbps-7US$注释：很多孟加拉商家都以接入BDIX为卖点，是指到BDIX的路由不限速，并不是可以提供BDIX的LAN，BGPlayer别想太多。
3、性能：差亿点能用。

5、路由：本次IP属于Purple IT Ltd（AS138358），国际走Summit Communications Ltd（AS58717）或tata（AS6453）。其中Summit Communications新加坡又接了不少好东西，所以国内延迟非常可观。

6、流媒体：原生，可惜南亚流媒体本来就不多，甚至YTB premium都没他的份。
7、总结：IP不错，路由也不错，可惜机器性能&网速实在是拉跨。再者我第一次开的机器没通网，我工单反馈又等了足足五天他们才给我重建一个正常的。所以说还是没脱离南亚大区优秀的匹配机制。
