What is routable and non routable IP?
Routable Networks Internet IP addresses are global in nature, and your end user device is able to access the Internet via the router. The router directs your traffic toward the relevant server. The term non routable just means exactly that; that IP packets cannot be directed from one network to another.
What is public and private IP range?

Why are 0 and 127 not used in Class A?
These two numbers, 0 and 127, are reserved and cannot be used as a network address. Class A addresses were intended to accommodate very large networks, so only the first octet is used to represent the network number. This leaves three octets, or 24 bits, to represent the host portion of the address.
What does IP 127.0 0.1 mean?
localhost
The term is a pseudo name for 127.0. 0.1, the IP address of the local computer. This IP address allows the machine to connect to and communicate with itself. Therefore, localhost (127.0. 0.1) is used to establish an IP connection to the same device used by the end-user.
