We know that there are three distinct classes of private IP addresses that were created to avoid IP exhaustion of IPv4. Why were there three distinct ranges that were created?
Assuming that the largest organization would be able to fit all its devices in a
10/8 network, is there any reason to even have the other classes? If there is such a large organization that uses the entire
10/8 block, wouldn't it have been possible to just use the next sequential segment like
11/x? Could all home and SOHO routers simply just use a private ip address like 10.0.0.1?
Additionally, assume that you have a small network with no VLANs or other uses for private IP addresses, is there an issue with using the entire 10/8 in DHCP in a home network besides being just wasteful (performance degradation or otherwise)?
