TCP/IP Subnetting Quick Tip

Here is a quick tip. Memorize the Private TCP/IP  address ranges. There will most likely be questions on the certification exams regarding information on RFC-1918 aka the private IP ADDRESSING ranges. There are 3 blocks of un-routable addresses you can use when designing your networks. Class A: 10.0.0.0 – 10.255.255.255 (10.0.0.0/8) Class B: 172.16.0.0 – 172.31.255.255 (172.16.0.0/12) Class C: 192.168.0.0 – 192.168.255.255 (192.168.0.0/16) These will help you in the exam when they ask you which is a valid private ip addressing scheme to use within your network. Beware of the trick questions when they ask what the masks are. I...

TCP/IP Subnetting

As I have mentioned before I have been working with computer networks for the past 10 years or so. One of the most challenging concepts that I have encountered while I studying to get my CCNA was learning how to Subnet and how to subnet the subnets using Variable Length Subnet Masks (VLSM). I quickly found out that if you do not have a solid foundation on how to subnet and how to use VLSM’s you will have a hard time understanding and implementing other networking features. These features would include IP Access Lists, Route Maps, Policy Maps, Distribution Lists…...

CCNA Training Tips

I have been studying networking for at least 12 years. It all started out in High School when Cisco had their CCNA 640-801 exam set. I have found it fascinating and knew that I would work in a fast paced career in computer networking. While I attended college at S.U.N.Y Ulster I studied both CCNA and CCNP material.  Most of the material was interesting while other material wasn’t. I found I had problems with Subnettings and ACL’s. Those two topics are something that you need have a rock solid foundation to build other skills on. After I finished college and...
