How do I use Java to ping a host?
Created May 8, 2012
John Zukowski Starting with Java 5, there is an isReachable() method in the InetAddress class. You can specify either a timeout or the NetworkInterface to use. For more information on the underlying Internet Control Message Protocol (ICMP) used by ping, see RFC 792 (http://www.faqs.org/rfcs/rfc792.html).
