Probably not, github being one of them makes git pulls a pain in the butt. The legacy french ISPs are also an pain in the butt, SFR having it not

Workaround : route IPv4 through a VPN

Yeah, not really the brightest idea, but it works pretty well. I use Zerotier, a server with both IPv4 and IPv6 connectivity and a nice ZT routing option :)

In this example, I use a server that has both IPv6 and IPv4 connectivity with the private ip 172.17.254.3 in the zerotier network, and my IPv6 only server will be .4

Define your default route in the zerotier network Advanced Managed Routes 2/128 0.0.0.0/0 via 172.17.254.3

Routing

IPv6 Layer​

6Only-server ============== IPv6 = Internet ============= IPv6 ============= 6&4 Server =========== Internet

IPv4 Layer​

-> route 0.0.0.0 -------- IPv4 - Zerotier ------------- IPv4 6&4 Server ------------- Internet

In the server, you must enable the following zerotier-cli option to allow a default route to be set for IPv4.

sudo zerotier-cli set ZTNETWORKID allowDefault=1
