Convert hexadecimal string to IP Address

Question

I want to convert a string value (in hexadecimal) to an IP Address. How can I do it using Java?

Hex value: 0A064156

IP: 10.6.65.86

This site gives me the correct result, but I am not sure how to implement this in my code.

Can it be done directly in an XSLT?

Answer 1

You can split your hex value in groups of 2 and then convert them to integers.

0A = 10

06 = 06

65 = 41

86 = 56

Code:

String hexValue = "0A064156";
String ip = "";

for(int i = 0; i < hexValue.length(); i = i + 2) {
    ip = ip + Integer.valueOf(hexValue.subString(i, i+2), 16) + ".";
}

System.out.println("Ip = " + ip);

Output:

Ip = 10.6.65.86.

Answer 2

try this

InetAddress a = InetAddress.getByAddress(DatatypeConverter.parseHexBinary("0A064156"));

DatatypeConverter is from standard javax.xml.bind package
