Just because CIDR happened doesn't mean that the subnet selection isn't relevant anymore.

- icedchai 6y agoHowever, classful subnet selection is not longer relevant today (A, B, C...) The Mac UI limited you to those three classful subnet masks. Today, it's much simpler to type /26 after your IP address instead of entering 255.255.255.192, or playing around with a non-standard host/network slider.
- duskwuff 6y ago> The Mac UI limited you to those three classful subnet masks. And it assumed a specific network architecture -- e.g, if you have a class A network, the middle two octets of your address represent a "subnet" and the last octet represents a "node". This may have been appropriate in pre-CIDR networks where all local nets were /24, but it's no longer true today; it's not uncommon to have networks which split on non-octet boundaries.
