For an IP or device that is in the local network, it's a very straight forward cache table lookup for its MAC address. How does

ARP work for an IP or a device which is in a remote network?

It doesn't really. The address is recognized as off the local network, so at the IP layer the packet is sent to the router, whose address is in the ARP table. As the packet travels to different hops, the MAC address is updated to the next hop.

N76 [4]

Answer:

Following are the code to this question:

//import package

import java.util.*;  

public class Full_XmasTree   //defining class

{        

// defining main method

public static void main(String as[])  

   {  

       int X,a,b; //defining integer variable

       Scanner obx = new Scanner(System.in); // creating Scanner class object

       System.out.print("Please enter: "); //print message

       X = obx.nextInt(); // input value from user

       for (a = 0; a < X; a++) //defining loop to print pattern  

       {

           for (b = X - a; b > 1; b--)//use loop for print white space  

           {

           System.out.print(" ");//print space

           }

           for (b = 0; b <= a; b++) // use loop to print values  

           {

               System.out.print("* "); //print asterisk values

           }

           System.out.println(); //using print method for new line

       }

   }

}

Output:

please find the attachment.

Explanation:

In the given java code, a class "Full_XmasTree" is declared, in which the main method is declared, inside this method three integer variable "X, a, and b", in this variables "a and b" is used in a loop, and variable X is used for user input.

  • In the next line, the Scanner class object is created, which takes input in variable X, and for loop is used to print asterisk triangle.
  • In the first for loop, use variable a to count from user input value, inside the loop, two for loop is used, in which first is used to print white space and second is used for the print pattern.

An IPv4 address has 32 bits, so there are 232 (over 4 billion) possible IPv4 addresses. Since the Internet is gaining devices qu
Vladimir [108]

Answer:

Explanation:IPv4 is almost used up due to the constant increase in devices so therefore IPv6 was implemented to combat this issue, IPv6 uses 128 bit addresses, allowing 3.4 x 1038 unique IP addresses. This is equal to 340 trillion trillion trillion IP addresses. IPv6 is written in hexadecimal notation, separated into 8 groups of 16 bits by the colons, thus (8 x 16 = 128) bits in total. Which essentially means both me and you wont see IPv6 run out in our life times nor will you kids kids.
