获取本地IP地址的主机名（java）

Question

I use this method in a loop to get the host name of 4 terminal in my local network identified by the ip address terminal[i].getIp() .

try {
 // Get hostname by textual representation of IP address
 InetAddress addr = InetAddress.getByName(terminal[i].getIp());

 // Get the host name
 String hostname = addr.getHostName();
} catch (UnknownHostException e) {
}

the problem here its that code take so long to return the result (up to 5 seconds) I wonder if there is another more optimized method.

Answer 1

Try the library from Google Guava, I think there are more optimized
