Resolving an IP Address.

by Jonetta N » Fri, 22 Sep 2000 04:00:00

I am curious as to how to resolve an IP Address using ASP and JavaScript.

1. Resolve Decimal IP Addresses with this Simple C Program

/* TURN A 32 BIT DECIMAL IP ADDRESS INTO 4 QUADS */
/* SPAMMERS CAN RUN, BUT THEY CAN'T HIDE */
/* Felix Tilley */

/* No Guarantees on how this will run on your computer. */
/* An unsigned long must be AT LEAST 32 bits for this to work */
/* An unsigned long must be AT LEAST 32 bits for this to work */
/* An unsigned long must be AT LEAST 32 bits for this to work */

/* NO JOKE */

#include <stdio.h>

main()
{
unsigned long webaddr, quad0, quad1, quad2, quad3, quotient, temp, remainder;

printf ("Enter web address as decimal: ");

scanf ("%lu", &webaddr);
printf ("\nWEB ADDRESS: %lu \n", webaddr);

quad0 = webaddr % 256;
quotient = webaddr / 256;

quad1 = quotient % 256;
quotient = quotient / 256;

quad2 = quotient % 256;
quotient = quotient / 256;

quad3 = quotient;

printf ("QUAD IP ADDRESS: %lu\.%lu\.%lu\.%lu \n", quad3,quad2,quad1,quad0);

printf ("\nHope this helps.\nFelix Tilley \n");

exit(0) ;
