Hello!

This is a funny little service that sends you one of
two 88x31 buttons, depending on if you use IPv4 or IPv6.

This are the buttons:
IPv4: https://ipvhuh.öwö.de/v4
IPv6: https://ipvhuh.öwö.de/v6

Just embed https://ipvhuh.öwö.de as an image,
like this:

<img src="https://ipvhuh.öwö.de" />

This will display the correct button for each visitor.

If you have new style ideas, or want to contact me for
any other reason, email me at johannes@jojojux.de

If you want to host this yourself,
use something like this Caddyfile:

example.com {
    header Cache-Control "no-cache"
    root /path/to/files

    @ipv4 client_ip 0.0.0.0/0
    rewrite @ipv4 /ipv4.png

    file_server {
        index ipv6.png
    }
}
