Functions

func DialTCP

func DialTCP(address string, dnsserver string) (net.Conn, error)

通过指定的dnsserver查询dns, 返回和address的TCP连接 e.g. address www.baidu.com dnsserver 8.8.8.8:53

Windows下，会直接使用调用系统的dns查询，不会生效
其它系统，会从8.8.8.8:53查询到对应ip，并与之建立TCP连接

以下为解释： https://pkg.go.dev/net#hdr-Name_Resolution Windows下总是会调用C库，所以无法指定

https://github.com/golang/go/issues/22846 容器里需要注意新建 /etc/nsswitch.conf文件

	echo "hosts: files dns" > /etc/nsswitch.conf

	Android Termux, 如果不指定dnsserver, 则默认会去读取/etc/resolv.conf
 问题是该文件不存在, 或者是没有权限读取, 默认dns server [::1]:53, 那么肯定失败

echo "nameserver 114.114.114.114" > /etc/resolv.conf
