It seems obvious, but maybe it shouldn't be an implicit assumption.<br>
<br>
Strictly speaking, IPv4 doesn't have to be replaced. It could run in
parallel with IPv6 for ages. Maybe it will slowly wither away or maybe
it'll be hacked to keep working. <br>
<br>
If ARIN intends to replace IPv4, it should say so in a policy. (If it's
not, that's another matter). Eventually this will have to drive
requirements, including dates to stop processing requests for new IPv4
addresses, administration, transfers etc. It may seem arbitrary to set
a deadline, but a lot of software related decisions are like that.
Microsoft could continue to support Windows 95 or legacy products
forever, it's "arbitrary" in a sense that they could in theory support
those systems forever, but they have business reasons for not doing so.
<br>
<br>
If you're an ISP, you know from Cisco or Juniper when your router is
end-of-life'd. You can buy support on it for a several years later
(often at increasingly silly costs). At some point there's no support,
no new warranties or software available for that hardware.<br>
The point is you know well in advance, you can stockpile spares and
keep running or replace with new gear. <br>
<br>
Is ARIN going to support IPv4 forever? At some point they can not give
out IP addresses, but they can deal with the transfers and other
administration, collect (increasingly steep) fees and maybe delve into
reclaiming unused address space etc. <br>
<br>
Is this the consensus? <br>

Like I said, it's implied.

Implicit, yes.
No point being a registry of internet numbers
