PlatformIO IDE

Hello Everyone, I’m trying to use IPv6 with my ESP8266 and I’ve success using Android IDE and setting the IwLP Variant to v2 IPv6 Lower Memory but I can’t reuse my code in PlatformIO and I doesn’t found how to set the IwLP Variant in PlatformIO.

The error that I’m receiving while I try to compile my code:

src/main.cpp:61:3: error: 'IP_ADDR6' was not declared in this scope; did you mean 'IP_ADDR4'?
   61 |   IP_ADDR6(&ip6_dns, PP_HTONL(0x20014860UL), PP_HTONL(0x48600000UL), PP_HTONL(0x00000000UL), PP_HTONL(0x00008888UL));
      |   ^~~~~~~~
      |   IP_ADDR4

Does anyone already had this error and found a solution? Thanks
