Does TinyGSM support IPv6 / IPv6-only cellular networks?

[sri122003]

Hi

I am using TinyGSM with a SIMCOM A7672 (LTE Cat-1) modem.

On Jio LTE (India), the APN provides IPv6-only PDP contexts:
CGDCONT: 1,"IPV6","jionet..."

Using the modem’s internal MQTT (AT+CMQTT*), MQTT connects successfully,
which suggests IPv6 connectivity is working at the modem level.

However, when using TinyGSM (TCP sockets + PubSubClient),
the connection never succeeds.

Could you please confirm:

1. Does TinyGSM currently support IPv6 sockets?
2. Is TinyGSM expected to work on IPv6-only cellular networks (e.g. Jio LTE)?
3. If not, is IPv6 support planned or explicitly out of scope?

Thank you for your work on TinyGSM.

As far as I know, it isn't supported. I also had some trouble with IPV6 in Korea.
