Your DNS is broken and returning the wrong IP address for git.centos.org. That's an RFC1918 address. Are you behind a firewall/proxy server? How you get out from behind that is something you'll have to ask your network admins.

I think this is a misconfiguration on git.centos.org. Something to do
with the DNS cache not up to date or something.

$ GIT_CURL_VERBOSE=1  git clone   https://git.centos.org/git/rpms/kernel.git
