DMIT好不好？前面讲了如何购买dmit的vps，因为买到手了，那么就来做个测评吧。机器价格不便宜，据说是三网双程CN2 GIA线路，原生美国IP，可以解锁奈飞等。
测评机器是PVM.LAX.Pro.BUILDERv2这一款。遗憾的是，香港的vps一直处于无货状态，大鸟跟踪很久，发现一直没有上新。如果不会上车，可以看之前的教程。
- DMIT服务器购买和使用指南 – 这家的VPS价格略高
1、机器配置
测评机器配置如下：
- 2 vCPU
- 2 GB RAM

9、最后
服务器性能：CPU是AMD EPYC 7402P 24-Core，磁盘IO很不错，可以满足建站要求！
网络情况：三网CN2 GIA，不过移动去程走的是Cogent！
价格情况：价格不算便宜！不过是CN2 GIA线路，所以贵有贵的道理
支付方式：支付宝，微信，信用卡、paypal
能否建站： 可以，并发能力很强悍。
视频解锁：美国原生IP支持解锁OTT平台如NF等，但是商家无法保证每个IP都可以解锁。
工单服务：客服还是很不错的，回复还是比较快的。
