I have not personally tested this, but I believe that ETA will do so, if you build RTSDK from source code, that is available on
with the option for IPV6 enabled.
I am looking at make/build files for RTSDK 2.0 "CMakeCache.tt")
"/Define if you want to enable IPv6 support
Consequently, if you need this option, please build from source with the option ON and test.
Hope this helps
