If the issue had been as prominent when the Windows Vista/7 networking stack was overhauled, I think we might have gotten some traction with Microsoft to get the Class E address space opened up as a...

1) @IPv6Freely; IP Classes are dead. No one should ever reference them unless they are speaking of a time when they weren't dead. VLSM and CIDR have been around nearly 20 years obsoleting classful...

@ancker While I have some sympathy for the "if your code is broken then fix it" point of view this doesn't work at a global scale.As Stretch says in the post: If the 240/4 block had been reclassified...

There are other ranges that could be allocated as well. Such as 198.19/16 -- although I do still enjoy using that for my home network. (its reserved for testing iirc) I mainly use it to allow full...

And who was the genius who decided to assign 16 million addresses for a loopback?268 million addresses is quite a bit. 'reserved for future use'? 'reserved for absolutely nothing' is more like it

classfull addressing is still a valid topic when learning subnetting for the CCNA. I don't see how one could learn the topic without knowing classfull addressing. knowing the default subnetmask for...

@Aaron: I'm not convinced.What's the use in distinguishing between "network bits" and "subnet bits" ?Sure, CCNAs need to learn how many hosts can fit in a /27, as well as how to find the network and...

To drive home the fact that IPv4 classes are irrelevant: IPv6 has no concept of address class, yet we can teach how to segment and summarize IPv6 prefixes just fine.

One little place classful addressing is still in use- the "network" command in routing configs.If your network is "classful", you don't have to spec the mask. If it's not, then you do.:)

I'm not aware of the CCNA "requiring" knowledge of classful address ranges when calculating addressing schemes and masks. I certainly don't teach it. However, as pointed out, it has to be mentioned...

At some point, when IPv6 really starts to gain steam, and big business makes the shift there should be gobs and gobs of IPv4 address space to reclaim. As time passes and more and more IPv6 gets...

If changes to network stacks had been to accommodate for the E block back in 2010, when we were supposed to be running out of IP addresses, it would be widely implemented now in 2015. IPv6 is still...

I would start a change.org petition to open up the E block for some sort of use if I knew who to send it to, since I would be surprised if IPv4 is not still being used in a significant way 25 years...
