Put some (final) fields in your doPing class, and a constructor that initializes them, then pass the values you want to use in call() to the constructor of doPing:

public class DoPing implements Callable<String>  {
     private final String ipToPing;

     public DoPing(String ip) {
         this.ipToPing = ip;
     }
     
     public String call() {
         // use ipToPing
     }
}
