Angelcam doesn't support cameras that can be reached only by IPv6 address.
However, you can still connect your cameras being on IPv6 address using Angelbox or Angelcam Ready Cameras.
We're constantly monitoring IPv6 adoption and demand so let us know if you need IPv6 support for your use case.
Still need further assistance? Why not check out our Angelcam Community, where you can connect with other users who are sharing their own experiences and insight into various Angelcam topics and problems.
