Hi, I'm not sure what routers you are buying, but a router being IPv6 ready has not been a problem for quite a few years now. One of the IPv6 allocations of my employer has been visible since April 2007, and so far we never paid more for IPv6-ready devices. https://stat.ripe.net/widget/routing-history#resource=2001%3A8d8%3A%3A%2F32 I have never seen a router that cost more for IPv6 capabilities or saw IPv6 compatibility advertised as a bleeding-edge feature by any vendor in my professional career. Even the historical Catalyst 6500 series had native IPv6 support and could handle a full global routing table in their time. On Tue, May 27, 2025 at 4:09 PM Alexey Berezhnev <alex@mac3.ru> wrote:
Hi,
While I appreciate the perspective, I’d suggest that many of those “big ISPs” who are reluctant to implement IPv6 are not simply unmotivated — they are being rational.
If you’ve ever priced out true dual-stack backbone-grade routers — the kind required to maintain IPv4+IPv6 parity at scale — and accounted for the fact that these setups must be duplicated to meet modern HA/availability requirements, you’d probably hesitate to “invest” in IPv6 too.
The capital expenditure is not trivial. Vendors don’t discount IPv6-ready hardware because it’s the “future.” On the contrary, the complexity, licensing, and redundancy expectations only add to the financial and operational burden.
So it’s not always about lacking motivation — sometimes it’s just about responsible budgeting.

Hi.
I want to remind, that here in THIS mail list members from various big international ISPs PUBLICLY admitted, that they have no intent to implement IPv6 because they have no motivation to do so. They have huge subnets of IPv4 and 0 interest in investing to IPv6.
On the other side are (mostly newer) members who already implemented IPv6 everywhere and can be totally happy with that, but IPv6 adoption is low and they have no technical ability to not have IPv4.
Charging for resources in my view can help with that. Also slightly balancing expenses between small and large ISPs - so small town ISP will not finance huge RIPE projects like atlas etc.
As for the proportions - as far as I know it is illegal (for tax purposes) for RIPE to charge proportional to resource amounts so some kind of “levels” should be. But here I might be wrong or misinformed.

I hear that since many years, but the reality in the countries i'm active in
(like Middle East, Africa) "far" from Europe is far from any near or mid-term
IPv6 adoption for many reasons. Primary reason is: the local big players are
grown historically on IPv4 which scarcity now gives them a huge local market
advantage or (oftean hear that vpices as well there) IPv6 does not give them
any commercial advantage.
But even in big european (non IT) enterprises (hoarding huge amounts of
unused public IPv4 space) i see no interest in the implementation of IPv6 in
the near to mid term (even in their internal networks).
IPv6 is - nor today nor in the near future - no solution to the problems
