<div dir="ltr">we use RFC6598 addressing and CGNAT on the edge unless someone pays for an IP. Very slowly getting IPv6 implementation down. Poor CRM/Shaper support for it being a big struggle. Preseem+UISP for example requires that whatever is handling IPv6 PD be pollable from preseem so they can grab MAC:PD prefix and combine them. VISP has implemented this better recently but I haven't fully implemented yet, that's a goal for this month.<br><br>We don't 'tunnel' ie no MPLS/VPLS, SRV6, EVPN right now. We technically do GRE tunneling, terragraph works just like OSPFv3 on IPv6 w/ GRE tunnels. <br><br>Part of the reason not to tunnel is that we don't have a single headend, we have regional POPs and interconnections between so we can reduce outages caused by the POPs. Fully routed seems to only non-convoluted way to handle this. Not interested in a VRRP moving my tunnel endpoint addresses between regions, that's a mess. And so we route.</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Oct 25, 2022 at 9:30 PM Dave Taht via LibreQoS <<a href="mailto:libreqos@lists.bufferbloat.net">libreqos@lists.bufferbloat.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">in my continued rip-van-winkle, living in the third world (california)<br>

ipv4 address supply and if you are deploying ipv6 to any extent?<br>
<br>
In all this discussion of multi-gbit fiber, my own direct experience<br>
is that AT&T's fiber rollout had very flaky ipv6, and more and more<br>
services (like starlink) are appearing behind cgnats, which have their<br>
own capex and opex costs.<br>
<br>
I see a lot of rfc1918 being used as the operational overlay<br>
elsewhere, tons of tunnels, also.<br>
