Functions ¶
func ParseIP ¶
ParseIP parses an input IPv6 address to retrieve its IPv6 address prefix and EUI-48 or EUI-64 MAC address. ip must be an IPv6 address or an error is returned.
Example ¶
ExampleParseIP demonstrates usage of ParseIP. This example parses an input IPv6 address into a IPv6 prefix and a MAC address.
// Example data taken from:
// http://packetlife.net/blog/2008/aug/4/eui-64-ipv6/
ip := net.ParseIP("fe80::212:7fff:feeb:6b40")
// Retrieve IPv6 prefix and MAC address from IPv6 address
prefix, mac, err := ParseIP(ip)
if err != nil {
log.Fatal(err)
}
fmt.Printf(" ip: %s\nprefix: %s\n mac: %s", ip, prefix, mac)
Output: ip: fe80::212:7fff:feeb:6b40 prefix: fe80:: mac: 00:12:7f:eb:6b:40
func ParseMAC ¶
ParseMAC parses an input IPv6 address prefix and EUI-48 or EUI-64 MAC address to retrieve an IPv6 address in EUI-64 modified form, with the designated prefix.
An error is returned if prefix is not an IPv6 address with only the first 64 bits or less set, or mac is not in EUI-48 or EUI-64 form.
Example ¶
ExampleParseMAC demonstrates usage of ParseMAC. This example parses an input IPv6 address into a IPv6 prefix and a MAC address.
// Example data taken from:
// http://packetlife.net/blog/2008/aug/4/eui-64-ipv6/
prefix := net.ParseIP("fe80::")
mac, err := net.ParseMAC("00:12:7f:eb:6b:40")
if err != nil {
log.Fatal(err)
}
// Retrieve IPv6 address from IPv6 prefix and MAC address
ip, err := ParseMAC(prefix, mac)
if err != nil {
log.Fatal(err)
}
fmt.Printf("prefix: %s\n mac: %s\n ip: %s", prefix, mac, ip)
Output: prefix: fe80:: mac: 00:12:7f:eb:6b:40 ip: fe80::212:7fff:feeb:6b40
