Does gtp5g support ipv6

I checked the included source code, and found that the UPF context has both GTP ipv4 and ipv6 device list. But I remember somewhere I read that the gtp5g module doesn’t support ipv6.

Who can tell how to get it working for both?

gtp5g didn’t support IPv6. As I know, for now, free5gc doesn’t support IPv6 neither.
