A fresh approach to IPv4 implementation
A fresh approach to IPv4 implementation
Public IP ranges are available in sets with a default mask of 255.255.255.0. Organizations requiring more can purchase additional blocks. Ranges A through D each have specific boundaries: A covers 1.0.0.0 to 9.255.255.255, B spans 10.0.0.0 to 10.255.255.255, C extends from 11.0.0.0 to 126.255.255.255, and D includes 127.0.0.0 to 127.0.0.255. Public addresses are reserved for internal use only with a default mask of 255.0.0.0. This configuration eliminates 310 million addresses while staying within the limit of 2^32 addresses. It also resolves the issue of 16 million loopback entries and removes private ranges like 192.168.0.0 to 192.168.255.255, opting instead for 10.0.0.0 to 10.255.255.255.
Engaging with outdated technologies and damaging existing systems is less advantageous compared to planning a shift toward IPv6. Some organizations currently hold vast /8 address blocks; releasing them would be more beneficial than attempting to repurpose address space in such a way.
Just checking if looking back would help me improve my approach.
I don't understand why, but that's the situation. You might remove millions of IP addresses from AT&T, Apple, Ford, Comcast, and the DoD—each holding 16 million public IPs—and even more from other sources. Just adjust which addresses are public or private and let other companies access them.
The selection of each private address range was guided by IANA's allocation strategy: three distinct blocks were reserved for private networks. The first range, 10.0.0.0 to 10.255.255.255, serves as a 10/8 prefix; the second, 172.16.0.0 to 172.31.255.255, acts as a 172.16/12 prefix; and the third, 192.168.0.0 to 192.168.255.255, functions as a 192.168/16 prefix. These divisions help organize and manage private IP addresses efficiently.
Aim to enhance the world by letting go of those rigid network rules that force strict subnetting. Think: "Hey, use 255.255.0.0... it’s your range, not mine. It’s private. Your switch should handle it." When challenged, clarify your perspective on small businesses and VLAN usage.
Keep in mind, those specific addresses aren't allowed in the larger subnets, "since they're not permitted."
