O.T. ::1 OPTIONS in access.log

Anyone an idea how I would have to interprete the following line in my access.log:

::1 - - [27/Jun/2023:09:25:04 +0200] "OPTIONS * HTTP/1.0" 200 140 "-" "Apache/2.4.29 (Ubuntu) OpenSSL/1.1.1 (internal dummy connection)"

::1 is the IPv6 loopback address (for connecting to the local computer).

This is apparently caused by this Apache feature:
