@hadfl are there issues with zadm and ipv6 ?

I keep seeing `[2024-09-02 07:00:58.76739] [21659] [warn] WARNING: Connect timeout` but `curl -4 downloads.omnios.org/media/img.json` and `curl -6 downloads.omnios.org/media/img.json` both work and download the same content

If I disable ipv6 only curl -4 works (expected) but zadm works too
