Right here. Screaming into the avoid begging for help. Some special
As a group that you'd consider a "little" guy, we've always ran full dual
stack ipv4/ipv6. The issue is being dual stack literally takes twice as
long to configure everything, it causes twice as many potential routing
problems, and you must now monitor twice as many routes, etc.. As a little
guy who has to fight tooth and nail for every customer, we hardly have time
in the day to run it this way, but we do, and guess what, every single day
we get ipv4 issues. Not CGNAT ipv4 issues, we actually have not seen a
single issue with CGNAT for our customer base, our techs ask a simple
question at install, "what do you use the internet for?", "gaming", "Okay,
dedicated public it is". And yet, with all those publics out there, we
still get calls everyday about some site not letting them in. It's all ipv4
issues. So not only do we have to expend the energy to implement dual stack
in our network, it doesn't save us any headaches. Until web hosting
companies, and cloud services offer ipv6 only as the defacto instead of the
premium service, only then will you see ipv4 not be an issue on the web.
The reason you only see the little guys screaming into the void is because
the big guys already have the contacts and already have the pull to get it
resolved in hours. I've posted in another forum the need for us as an
industry to have an association directly in charge of maintaining contacts
at all associations that have a history of aggressive filtering, so issues
like these don't take a little guy like us 2-4 weeks to resolve. If the
little guys were all a part of this association, they would contact their
membership rep for the contact and the membership rep would reach out as a
representative of the group as a whole to resolve any IP filtering issue
that occurs. Anything less than that will continue to have this forum
clogged with requests like these.
