How to refresh hosts file without rebooting
You don't need to reboot. Any changes you make to the hosts file are immediate. You used to need to reboot for changes to take effect in Windows 9x. That is no longer the case.
However, you may need to restart any applications that do internal hostname or DNS caching, such as web browsers.
Have you tried ipconfig /flushdns ? I haven't found the need to reboot, though.
Just a warning, NSLOOKUP will still retrieve results from DNS Server will never look at hosts file; To check if your new name works try the ping command.
使用tracert -d命令追踪域名的解析，发现是可以解析的。
