Support for IPv6, including mixed IPv6/IPv4 operation?

Postby pfister@oberon.ch » Thu Sep 29, 2016 9:39 am

Is it planned to support IPv6 in the foreseeable future? We would need mixed IPv4/IPv6 operation.

And if this is not planned, how difficult would it be to port another IP stack to the ESP32?

With best regards

LWIP actually already supports IPv6; at the moment, it's just the DHCP bit (server as well as client) that aren't IPv6-compatible yet. Support for complete IPv6 is planned, but unfortunately I can't tell you the timeframe on that.

Doesn't it support SLAAC though so is DHCPv6 necessary?

But also simultaneous use of IPv4 and IPv6 connections?

And would it be feasible/hard/easy to adapt another IP stack instead?

Thanks

As far as I am aware, LWIP is capable of simultaneous IPv4 and IPv6 operation. LWIP is included as source code in esp-idf, so it should be possible to replace it with something else. I can't comment on the ease with which you'd be able to do that, though.

Not to revive an old thread, but I hate creating new ones for the same thing. Do we know if DHCPv6 or SLAAC has been implemented yet?

SLAAC is supported, DHCPv6 is not.

I'm going to assume that is on the IDF side of the house, not Arduino. I tried earlier and changed a VLAN from DHCPv6 to SLAAC but still couldn't get a v6 address. Any tips?
