Get Host Name by IP Address using Java

This Java tutorial shows how to get the host or domain name by IP address using Java.

To get a host or domain name, you will need to get an instance of InetAddress. In this case, we will provide a string representation of an IP address. Once we have an instance of InetAddresss we can request the host or domain name using the getHostName() method.

NOTE: The getHostName() method may not be able to resolve the host name for the specified IP address. If this occurs, getHostName() will return the IP address.

//Get an instance of InetAddress for the IP address
InetAddress inetAddress = InetAddress.getByName("208.29.194.106");

//Get the host name
String ipAddress = inetAddress.getHostName();

//Print the host name
System.out.println(ipAddress);
