Maiko,
That was in fact my proposal. Have ARDC setup a mesh of routers over the world for
everyone to connect to (instead of requiring the IPIP mesh), have the node at UCSD
advertise 44.0.0.0/9 and 44.128.0.0/10, and optionally have local routers advertise
large chunks of address space like country subnets via the ISP where they are located.
Easy to setup, with some scripting to allow simple addition of new users.
Only then it was made more and more complicated and people thought they could score
points by making remarks like "but we need to get an AS number!". Others want
to
rule out everything that does not have enterprise/bank grade availability.
That quickly made the idea more and more complex and usually when that happens
the whole idea is eventually abandoned or at least postponed indefinitely, and we
remain stuck in the past.
W.r.t. the VPS I was referring to the commonly known VPSes run under Apache Aurora
and similar. Those cannot do IPIP (or symmetric GRE or whatever tunnel not running
over TCP or UDP). People getting a $3/mon VPS often find this out once they get it
deployed. When you have a more directly managable VPS it will not have this problem.
But I do not want to force everyone with an unsuitable home internet connection to
get a suitable VPS, run IPIP from there, and then setup a VPN to that VPS, all because
we have done IPIP for 25+ years and now want to continue it indefinitely.
