var ( // Service to resolve IP address against. DefaultTargetIPv4 string = "https://v4.ip.ac-x.eu" DefaultTargetIPv6 string = "https://v6.ip.ac-x.eu" // UserAgent DefaultUserAgent = "catinello.eu/inet" )
Functions ¶
func Connectivity ¶
Connectivity returns boolean values for online IPv4 and IPv6 state respectively.
Example ¶
package main
import (
"fmt"
"log"
"catinello.eu/inet"
)
func main() {
var ip4, ip6 bool
if inet.DualStack() {
ip4, ip6 = inet.Connectivity()
} else {
if inet.HasIPv4() {
ip, err := inet.GetIPv4()
if err != nil {
log.Fatal(err)
}
if ip.IP().IsGlobalUnicast() {
ip4 = true
}
}
if inet.HasIPv6() {
ip, err := inet.GetIPv6()
if err != nil {
log.Fatal(err)
}
if ip.IP().IsGlobalUnicast() {
ip6 = true
}
}
}
fmt.Println(ip4, ip6)
}
Output: true true
func DualStack ¶
func DualStack() bool
DualStack returns a boolean value. It retursn true, if the system has a global unicast addresses for IPv4 and IPv6.
func GetIPv4 ¶
GetIPv4 returns the retrieved pulbic IP and nil or an occured error.
Example ¶
package main
import (
"fmt"
"log"
"catinello.eu/inet"
)
func main() {
ip, err := inet.GetIPv4()
if err != nil {
log.Fatal(err)
}
fmt.Println(ip.IP().IsGlobalUnicast())
}
Output: true
func GetIPv6 ¶
GetIPv6 returns the retrieved pulbic IP and nil or an occured error.
Example ¶
package main
import (
"fmt"
"log"
"catinello.eu/inet"
)
func main() {
ip, err := inet.GetIPv6()
if err != nil {
log.Fatal(err)
}
fmt.Println(ip.IP().IsGlobalUnicast())
}
Output: true
func HasIPv4 ¶
func HasIPv4() bool
HasIPv4 returns a boolean value as true, if the system has a global unicast IPv4.
