IsPrivate() function is used to check whether IP is a private address or not. IsPrivate() function is of net package.
function prototype:
func (ip IP) IsPrivate() bool
Return type:
IsPrivate() of net package in go returns true if IP address is a private address else false.
Example:
package main
import (
"fmt"
"net"
)
func main() {
// Check IPv4 address is a private IP or not
ipv4_ip := net.ParseIP("10.10.10.2")
is_private_addr := ipv4_ip.IsPrivate()
if is_private_addr == true {
fmt.Println("10.10.10.2 is a private IP address.")
} else {
fmt.Println("10.10.10.2 is not a private IP address.")
}
ipv4_ip = net.ParseIP("11.0.0.0")
is_private_addr = ipv4_ip.IsPrivate()
if is_private_addr == true {
fmt.Println("11.0.0.0 is a private IP address.")
} else {
fmt.Println("11.0.0.0 is not a private IP address.")
}
// Check IPv6 address is a private IP or not
ipv6_ip := net.ParseIP("fc00::")
is_private_addr = ipv6_ip.IsPrivate()
if is_private_addr == true {
fmt.Println("fc00:: is a private IPv6 address.")
} else {
fmt.Println("fc00:: is not a private IPv6 address.")
}
ipv6_ip = net.ParseIP("fe00::")
is_private_addr = ipv6_ip.IsPrivate()
if is_private_addr == true {
fmt.Println("fe00:: is a private IPv6 address.")
} else {
fmt.Println("fe00:: is not a private IPv6 address.")
}
}
Output:
10.10.10.2 is a private IP address. 11.0.0.0 is not a private IP address. fc00:: is a private IPv6 address. fe00:: is not a private IPv6 address.
