mosdns/pkg/upstream/utils.go

Lines 61 to 75 in a281fdb

 // trySplitHostPort splits host and port. 

 // If s has no port, it returns s,0,nil 

 func trySplitHostPort(s string) (string, uint16, error) { 

 var port uint16 

 host, portS, err := net.SplitHostPort(s) 

 if err == nil { 

 n, err := strconv.ParseUint(portS, 10, 16) 

 if err != nil { 

 return "", 0, fmt.Errorf("invalid port, %w", err) 

 } 

 port = uint16(n) 

 return host, port, nil 

 } 

 return s, 0, nil 

 }

代码应该是这一块。但似乎不加方括号的v6并不能正确识别，只是最后一段是数字的话不会触发报错

直接把IPv6写进DoH的URL也有一样的问题，需要补上端口号才能正常使用，这种写法https://[2606:4700:4700::1111]/dns-query会报证书错误
目前能使用的写法：https://[2606:4700:4700::1111]:443/dns-query
