Configure git to use IPv4 instead of IPv6 by default

Question

Checking the environment variables and also HTTP configuration options does not reveal something. Is there a way to do this?

Answer 1

In 99% of cases, you should not be doing this. The real answer to the question is fix your IPv6 connection.

Failing that, you can edit /etc/gai.conf to prefer IPv4 over IPv6. gai.conf modifies the behaviour of getaddrinfo(), which almost all IPv6–supporting applications use to resolve hostnames.

Almost all systems ship with a copy of /etc/gai.conf within their glibc or libc package. If it is missing from /etc, usually I find a template copy is lurking somewhere within /usr/share/doc, for you to copy into /etc and modify accordingly.
