Networking Primer -IP Addressing

An IP address is a unique logical identifier for a node or host connection on an IP network. An IP address is a 32 bit binary number, and represented as 4 decimal values of 8 bits each. The decimal values range from 0 to 255. This is known as "dotted decimal" notation.

Example: 192.189.210.078

It is sometimes useful to view the values in their binary form.

192     .189     .210     .078
11000000.10111101.11010010.01001110

Every IP address consists of network identifier and node identifier. The IP network is divided based on Class of network. The class of network is determined by the leading bits of the IP address as shown below. 

Address Classes

There are 5 different address classes. You can determine which class any IP
address is in by examining the first 4 bits of the IP address.

• Class A addresses begin with 0xxx, or 1 to 126 decimal.
  
• Class B addresses begin with 10xx, or 128 to 191 decimal.
  
• Class C addresses begin with 110x, or 192 to 223 decimal.
  
• Class D addresses begin with 1110, or 224 to 239 decimal.
  
• Class E addresses begin with 1111, or 240 to 254 decimal.

Addresses beginning with 01111111, or 127 decimal, are reserved for loopback and for internal testing on a local machine. Class D addresses are reserved for multicasting. Class E addresses are reserved for future use. They should not be used for host addresses.

Now we can see how the Class determines, by default, which part of the IP address belongs to the network (N) and which part belongs to the Host/node (H).

• Class A: NNNNNNNN.HHHHHHHH.HHHHHHHH.HHHHHHHH
  
• Class B: NNNNNNNN.NNNNNNNN.HHHHHHHH.HHHHHHHH
  
• Class C: NNNNNNNN.NNNNNNNN.NNNNNNNN.HHHHHHHH

In the example, 192.189.210.078 is a Class C address so by default the Network part of the address (also known as the Network Address) is defined by the first three octets (192.189.210.XXX) and the node part is defined by the last one octets (XXX.XXX.XXX.078).

In order to specify the network address for a given IP address, the node section is set to all "0"s. In our example, 192.189.210.0 specifies the network address for 192.189.210.078. When the node section is set to all "1"s, it specifies a broadcast that is sent to all hosts on the network. 192.189.210.255 specifies the broadcast address.

Private Subnets

There are three IP network addresses reserved for private networks. The addresses are 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. They can be used by anyone setting up internal IP networks, such as an intranet. Internet routers never forward the private addresses over the public Internet.

CCNA Intro and CCNA ICND exams.

There is a two-exam option for attaining ccna certification. Here, you need to pass two individual exams, namely CCNA Intro and CCNA ICND for attaining ccna certificate. This stream is useful for candidate who are new to networking, and prefer slower pace of study.
See CCNA Intro exam details, and CCNA ICND exam details
Download, and practice CCNA Intro exam questions, and CCNA ICND exam questions.

The combined syllabus for CCNA Intro, and CCNA ICND is close to CCNA. If you are a working professional with atleast 1 or 2 years of experience in networking, it is suggested to take single exam path. If you are completely new to networking, it is recommended to take two-exam path.

CCNA Exam Cram Notes

A quick revision notes for CCNA exam is available at examguides.com The ccna exam cram notes is useful for those who are in the final stage preparation.

ISO OSI reference model

A comprehensive tutorial is available at tutorialsweb on ISO OSI model. OSI model is the basic building block of CCNA certification preparation, and it is highly required that a CCNA aspirant has a solid understanding of different layers of OSI model. The contents of the tutorial are given below:

• The OSI (Open Systems Interconnection) Model
• Information Exchange Process
• Relationship between the OSI Model and Networking Devices
• Repeaters, Bridges, Routers, Gateways and other network components
• Glossary of Networking Terms

Read complete tutorial on ISO OSI model for CCNA preparation.

CCNA Network Simulator

CCNA Network Simulator is a software tool that simulates a router/switch network. The tool should typically be able to:

• Simulate a router
• Simulate a switch
• Simulate a router/switch network
• Design a router/switch network
• Save semi-finished configurations, and reload for later resumption
• Save the work to a text file for later use.

A router simulator is essential for having hands-on practice. Ofcourse, if you can buy routers and switches and make physical network that would be fine, but normally does not justify the costs involved.

CCNA network simulators are available from the following sources:

A comprehensive CCNA trainer is available at:

http://www.certexams.com/cisco/ccna/download/ccna-trainer.html

Normally, the software is available free for demo version, and you need to pay if you want to unlock the full version. The cost range from $150 down to $25 depending on the requirements. Download, and checkout the features available.

A guide to certification exams

An article is available at simulationexams.com on certification benefits. A brief review of contents is given below.
I. Benefits of Certification:
Recognition and increased job opportunity
Proficiency in Related Technology
Equipping a fresh out of college candidate to face a job
Increased job security, and remuneration - According to CertMag.com study, certified candidates enjoyed salary increase from 10% to as high as 23%. It is also shown that more the number of certifications (higher the skill level) more the amount of compensation. See the article at www.certmag.com/issues/dec00/feature_gabelhouse.cfm.
II. Leading vendor certifications from Microsoft®, CompTIA®, Cisco®, CheckPoint®, and Prosoft®:
Microsoft®, CompTIA®, Cisco®, CheckPoint®, and Prosoft® are among the leading vendors of IT Certifications. Each vendor, in turn may have different certification tracks. For example, Microsoft has MCSE (For Networkers) track, and MCSD (for Developers) track. Usually, each track has different levels of certification aimed at the beginner, the pro, and the expert. As often said, certification is a journey, and not a destination. In fact, many certifications require re-certification after a pre-determined period of time (usually 2-3 years) to remain certified. Therefore, it is important that you choose your certification track after careful consideration of your career plan. Though there are wide range of certifications available, we confine to a few leading certification tracks: MCSE/MCSA, CCNA/CCNP, A+/Network+, CIW, and CheckPoint CCSA/CCSE.
Anyone, who is interested in pursuing certifications is recommended to go through the article, and choose appropriate certification path. View Complete article at: Guide to IT Certifications and Certification Exams
