Hi,
I used the following code to create a InetAddress from lilnklocal
address ( returned by getifaddrs function).
try{
InetAddress add =
InetAddress.getByName("fe80::216:3eff:fe38:74e8%eth0");
}
catch(UnknownHostException uhe){
System.out.println("Caught unknownhost exception ");
System.out.println("Message: "+uhe.getMessage());
uhe.printStackTrace();
}
But it fails with the following message.

What could be the possible reasons for it ? Is it specific to JDK
version ?
The error message is quite clear - the DNS does not recognize the host
name. What you passed to the call really doesn't look like a host
name, so that seems unsurprising.
