A Little of Network

continue my first post in a few hours ago, this time I want to describe what about I will share in this site. a little of network mean a little very very little as long as I know about network, may be I often share about proprietary of cisco b'cause I often play & experiment in there.

first time I share allocating of IP address in network, IP address is like address of your home in real live or real world

Class A
range : 1.0.0.0 - 126.0.0.0

host every network : 16 777 216
first bit 0 in binary

Class B
range : 128.0.0.0 - 191.255.0.0
network : 16 384
host every network : 65 536
first 2 bit 10 in binary

Class C
range : 192.0.0.0 - 223.255.255.0
network : 2 097 152
host every network : 256
first 3 bit 110 in binary

Class D is Multicast

Class E is Research
