interfaces, err := net.Interfaces()
if err != nil {

return
}
for _, i := range interfaces {
fmt.Printf("Name : %v \n", i.Name)
// see http://golang.org/pkg/net/#Flags
fmt.Println("Interface type and supports : ", i.Flags.String())
}
}
Example 2:
ifaces, err := net.Interfaces()
if err != nil {
fmt.Print(err)
return
}
for _, i := range ifaces {
addrs, err := i.Addrs()
if err != nil {
fmt.Print(err)
continue
}
for _, a := range addrs {
switch v := a.(type) {
case *net.IPAddr:
fmt.Printf("%v : %s (%s)\n", i.Name, v, v.IP.DefaultMask())
