True Dual Stack with DHCPv6 prefix delegation (/56 to boot)

Hot on the tail of getting our new 100gbit core router and interchange switch up and running, we snuck in true IPv6.

We are the only ISP on the KPUD network with true IPv6 technology. Our technology is better than Comcast / Cox / Verizon / T-Mobile / Starlink who all use Carrier Grade NAT on the IPv4 addresses.

Your home router is assigned a unique global IPv6 (the next gen internet, native on cell phones and data centers) as well as a unique IPv4.

In addition to just having IPv6, we deployed IPv6 Prefix Delegation. We give your home router a block of 256 globally routable IPv6 networks to do as it pleases. This is called a /56 prefix delegation. Currently, most residential routers automatically put guest wifi on a seperate network from main network if prefix delegation actually works. Comcast hands out a /60 (16 networks) which isn’t RFC standards compliant. The folks at EERO (the home routers we exclusively sell/install for homes and simple small business) advise me that IPv6-PD is wildly broken in the world.

Getting proper prefix delegation to work was the holdup on our IPv6 deployment. Our old router (Ubiquiti EdgeRouter Infinity) didn’t support route injection for the delegated prefix into the route table. It would hand your router a block of addresses but not route the world to them. Kind of useless and counterproductive. Our new router supports proper delegation.

I am confident there is only a small subset of our customers who care/understand this blog post at all. But I know the ones that do are cracking open a beer, possibly doing a fist pump, and otherwise demonstrating their happy geek expressions.
