Configure git to use IPv4 instead of IPv6 by default

Issue

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

Solution

With git 2.8 (March 2016), you can force git fetch/push/clone to use IPV4 or IPV6.
(for git pull, see below Git 2.16, Q1 2018)

See commit c915f11 (03 Feb 2016) by Eric Wong (ele828).

connect & http: support -4 and -6 switches for remote operations

Sometimes it is necessary to force IPv4-only or IPv6-only operation on networks where name lookups may return a non-routable address and stall remote operations.

-4, --ipv4:

Use IPv4 addresses only, ignoring IPv6 addresses.

-6; --ipv6:

Use IPv6 addresses only, ignoring IPv4 addresses.


Update Git 2.16 (Q1 2018): Contrary to the documentation, "git pull -4/-6 other-args" did not ask the underlying "git fetch" to go over IPv4/IPv6, which has been corrected.

See commit ffb4568 (19 Nov 2017) by Shuyu Wei (“).

With Git 2.29 (Q4 2020), "git fetch --all --ipv4/--ipv6(man)" forgot to pass the protocol options to instances of the "git fetch" that talk to individual remotes, which has been corrected.

See commit 4e735c1 (15 Sep 2020) by Alex Riesen (ar-cetitec).

fetch: pass --ipv4 and --ipv6 options to sub-fetches

Signed-off-by: Alex Riesen

The options indicate user intent for the whole fetch operation, and ignoring them in sub-fetches (i.e. "--all" and recursive fetching of submodules) is quite unexpected when, for instance, it is intended to limit all of the communication to a specific transport protocol for some reason.
