Special and private IPv4 addresses

Показать описание
In this video, I will talk about some special IPv4 addresses, such as the very first one: 0.0.0.0, and the very last one: 255.255.255.255. What is link local address? What does it means if your computer has a link local address? Why do we say more than 16 million of class A IP addresses were wasted just for one loopback address? What are private IP addresses in Classes A, B, and C? Why do we need private IP addresses? What is the side benefit of private IPv4 addressing scheme? In this video, you may get all answers to these questions, and more…

A more labourious way to remember *16* and *31* in the second octet of class B private IP adresses is to think in binary and to remember the /12 mask:

lowest IP address : 127.16.0.0(decimal) 0111 1111. 0001 0000. 0000 0000. 0000 0000 (binary)

Now *remembering that the mask is /12* we deduce that *only the last 20 bits (32 -12) are the ones who change by spanning the entire range.*
*The highest IP address will be the one with all 1s in the "host" part of the address:*

highest IP address : 0111 1111. 0001( *this is the "network" part and remain the same* )1111. 1111 1111. 1111 1111 127.31.255.255(in decimal)
