Open source IPv6 Java validation

Question

Now that all sun.* proprietary APIs may be removed in the future, does anyone know any open source Java implementation of IPv6 validation?

Regarding this question, it'd be also nice to have native ipv6-address/prefix-length format support to.

Presumably, the APIs won't be removed until the Java platform provides equivalent functionality. Have you tried using `Inet6Address.getByAddress` or `InetAddress.getByName` as a validator? — Stephen C, Sep 03 '12 at 09:39
Maybe [this lib from Jan Van Besien](http://janvanbesien.blogspot.co.uk/2011/10/java-library-for-ipv6.html) ? — Stewart, Oct 31 '12 at 14:25
Caution: Inet6Address.getByName can lead to DNS queries if you feed e.g. a broken address like "::1::" into it. This can take a couple of seconds on a single call! — Dr. Hans-Peter Störr, Mar 25 '13 at 17:55

See the Guava library (there is isInetAddress() method)

The open-source IPAddress Java library will validate both IPv6 and IPv4 and also supports prefix-length (and validation of such). I am the project manager of that library.

Use

try {
    IPAddressString str = new IPAddressString("::1");
    IPAddress addr = str.toAddress();
} catch(IPAddressStringException e) {
    //e.getMessage has validation error
}
