Incredibly unsafe. If Class E is reserved "for future use", maybe that could include public use. The first rule of hardening production reliability is, make sure it doesn't just work, but that it will continue to work. Tomorrow, some customer of yours gets assigned addresses from Class E. Have fun untangling that.
Why not stop this bullshit and just transition to IPv6??
- jandrese 2y agoI'm not too worried about the Internet at large actually using Class E addresses. IPv4 is considered obsolete so there shouldn't be any "future use" coming out of the standards committee.
- unilynx 2y agoclass E can't ever be used on the public internet anyway. too many existing firewalls are already configured to drop anything with a source address in range 224.0.0.0-255.255.255.255 (class D and E)
- Hikikomori 2y agoThere's an RFC to use it in the Internet, unlikely to be ratified though. Usually because your provider does not fully support IPv6 yet, which is the case at least with Azure and AWS, likely Google as well.
