The "RFC" you're looking for is probably https://tools.ietf.org/html/draft-wilson-class-e-02, which was not agreed to and so has no RFC number. The fundamental issue that was raised during that discussion was that while repurposing class e would provide a few more IPv4 addresses and so delay the need to replace the IPv4 protocol for some period of time, APNIC's experience with a new /8 in 2011 (it was given the /8 in January 2011, and by April had largely distributed it to its members) suggests that the address space would be used up almost immediately if distributed publicly, and if used privately doesn't benefit the many networks that really honestly wish that we could squeeze more than 2^32 addresses into a 32 bit container.
I'd really suggest using IPv6. Networks like Reliance JIO in India, which has turned off or never turned on IPv4 for most of its services, find that they don't need IPv4 apart from customer preference. > On Mar 9, 2021, at 6:36 AM, Douglas Fischer <fischerdoug...@gmail.com> wrote: > > So, if an organization wants to use that, they will require from the vendors > the compliance with that RFC. > > > > Em ter., 9 de mar. de 2021 às 11:00, Forrest Christian (List Account) > <li...@packetflux.com> escreveu: > Back a little bit ago when the thread about running out of RFC-1918 space was > going on, I was going to make a suggestion about repurposing the Class E > space in the case where one ran out of space, assuming one could get the > vendors on your network to support this address range. > > I sort of discarded the suggestion just because of the whole issue of that > range being hardcoded as invalid in so many implementations that this didn't > seem all that useful. > > On the other hand, if you're large enough that you're running out of RFC-1918 > space you might be able to exert enough power over select vendors to get them > to make this work for selected purposes.
