IP Addressing and Subnetting Exercise 1. Write the default subnet Masks for the Class A‚ Class B and Class C IP addresses. 2. How we can distinguish Class A‚ Class B‚ Class C‚ Class D and Class E IP addresses from each other. Write the range of first octet in binary and decimal for all the 5 IP address classes 3. Write the default subnet Masks for the following IP addresses: a. 100.100.225.100 b. 200.0.0.2 c. 190.47.115.0 d. 192.11

Smallest number of /27 = 32. Therefore this has to be doubled 8 possible times till it reaches its maximum which is 224. All the subnet addresses with its subnet marks are listed

default subnet mask used with each‚ and the number of hosts for each. The three IP address classes are class A‚ class B‚ and class C. Default subnet mask for class A = 255.0.0.0 Default subnet mask for class B = 255.255.0.0 Default subnet mask for class C = 255.255.255.0 The number of hosts that class A can have is 16‚777‚214 The number of hosts that class B can have is 65‚534 The number of hosts that class C can have is 254 2) What is the subnet ID of host 86.212.118.145‚ given a subnet mask

useful methods for passing certification test questions. Overview of Subnetting The reason we subnet is to break larger IP networks into smaller ones. Often we have networks that are the same size. These use a fixed length subnet mask for all networks. Other network designs employ different subnet masks‚ depending on the number of addresses required for each subnet. This is called variable length subnet masking or VLSM. As I learned subnetting‚ I began to realize that subnetting is much like my

------------------------------------------------- Subnetwork From Wikipedia‚ the free encyclopedia Creating a subnet by dividing the host identifier A subnetwork‚ or subnet‚ is a logically visible subdivision of an IP network.[1] The practice of dividing a network into two or more networks is called subnetting. All computers that belong to a subnet are addressed with a common‚ identical‚ most-significant bit-group in their IP address. This results in the logical division of an IP address into two
