Output in CSV, IP is not displayed

[Epy]

Hi,
I'm testing a few commands with speedtest-cli. In CSV output there is no IP, despite it's available in verbose output:

2023-10-04T09:15:26.796756519+02:00;Virginia, United States, OVH;https://speed.riverside.rocks/;14;0.5;8.15;8.06;;

$ /opt/librespeed/librespeed-cli -4

You're testing from: {"processedString":"2a01:cb19:dca:300:dea6:32ff:fe90:c2b0 - Unknown ISP","rawIspInfo":""}

also it used IPv6 even if I asked IPv4. Sometimes it works.

I wanted to give you the version I'm using but:

$ /opt/librespeed/librespeed-cli --version

it's the last one, v1.0.10

Thanks for your help
