About Quote by Jon Postel
“One of the things that is not so good is that a decision was made long ago about the size of an IP address - 32 bits. At the time it was a number much larger than anyone could imagine ever having that many computers but it turned out to be to small.”
About This Quote
Source Technical: IPv4 design, 1970s, RFC 791
Early IP design assumed 32‑bit addresses would suffice, but exponential growth made them insufficient.
In simple terms: 32‑bit IP addresses proved too limited as the internet expanded.
Key Takeaway
