No IPv6 on Nodeup download URLs

Not really a bug, but I feel like I'm missing something. Kops can work in IPv6 only subnets but the startup sequence that downloads and runs Nodeup is served from hosts that have no IPv6 address. ``` bash[2156]: == nodeup node config starting == bash[2156]: == Downloading nodeup with hash cb2261d48a9a8918e67c1b2b762ae871feabafe4978c597b6583d37b9a8dc446 from https://artifacts.k8s.io/binaries/kops/1.35.0-beta.1/linux/arm64/nodeup,https://github.com/kubernetes/kops/releases/download/v1.35.0-beta.1/nodeup-linux-arm64 == bash[2156]: == Downloading https://artifacts.k8s.io/binaries/kops/1.35.0-beta.1/linux/arm64/nodeup using curl -f --compressed -Lo nodeup --connect-timeout 20 --retry 6 --retry-delay 10 == bash[2169]: % Total % Received % Xferd Average Speed Time Time Time Current bash[2169]: Dload Upload Total Spent Left Speed containerd[1855]: time="2026-04-06T17:43:31.896051030Z" level=info msg="Start subscribing containerd event" containerd[1855]: time="2026-04-06T17:43:31.896130537Z" level=info msg="Start recovering state" ``` Neither `artifacts.k8s.io` or `github.com` (lmao) have an IPv6 address. Is it because I am using ARM? are there any more mirrors?
