I'm wondering why I see haproxy running on ipv6 (Ubuntu 22.04): Excerpt from haproxy.cfg:
frontend http-in
# bind *:80
bind :::80 v4v6
# bind *:443 ssl crt /etc/haproxy/certs/xxxxxx.pem
bind :::443 v4v6 ssl crt /etc/haproxy/certs/xxxxxx.pem
bind [email protected]:443 name quic443 ssl crt /etc/haproxy/certs/xxxxxxx.pem
proto quic alpn h3,h3-29,h3-28,h3-27 npn h3,h3-29,h3-28,h3-27 allow-0rtt curves

In my haproxy.log I see:
Nov 28 16:10:19 mail haproxy[59727]: ::ffff:88.181.85.41:63772
[28/Nov/2023:16:10:19.728] http-in http-in/<NOSRV> 0/-1/-1/-1/0 301 97 - - LR--
1/1/0/0/0 0/0 "GET / HTTP/1.1"
This stems from a request I did that way:
curl http://www.kukulies.org
Comments welcome.
