Really weird problem with internet

I’m trying to host a vpn access server using docker, but while trying to do this i ran into a problem which a have made https://github.com/kylemanna/docker-openvpn/issues/489 a github issue about. While trying to find what could be causing this issue i have found that running ping url/ip always gets a response even from ip’s that shouldn’t be responding. The response time is also extremely low, and not realistic for my network setting.
I have done the same thing with the same response in an alpine container.
link to logs when pinging (you can enter any ip you want and the response is all the same):
response when pinging a local ip on my network that has no actual device attached to it:

I get the exact same response when pinging a site such as google.
