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...

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…...

RTA Update 12/8/12

Today was an okay day.  I didn’t go to sleep until 4:00 A.M. The time I woke up was at 3:00 p.m. Shortly after waking up I took my medicine for the sinus infection that has been keeping me home. I got dressed and accompanied my Mom to the mall to buy some printer ink and other office supplies. After we left the mall we went to KFC/LJS to get some dinner for the 3 of us. The food was decent though I was feeling agitated for the greater part of the day. I felt very jittery as if I...
