A simple DNS lookup in Java import java.net.InetAddress; import java.net.UnknownHostException; public class DNSLookup { public static void main(String... args) { InetAddress inet = null; try { final String host = "eradicus.blogspot.com"; inet = InetAddress.getByName(host); System.out.println("DNS Lookup: " + host); System.out.println("IP Adress: " + inet.getHostAddress()); } catch (UnknownHostException e) { e.printStackTrace(); } } } By using the InetAddress API you will be able to obtain the IP address of the target.

Linked list is one of the most popular data structures in Computer Science . Read more about linked lists [here] . In this entry we will write a function to reverse a linked list in C++ efficiently. Link* reverse_list(Link* p) { if (p == NULL) { return NULL; } Link* h = p; p = p->next; h->next = NULL; while(p != NULL) { Link* t = p->next; p->next = h; h = p; p = t; } return h; } Enjoy.
