IPv6 support

Shelly is gradually introducing IPv6 support for Gen2 Pro devices and Gen3 devices:

  • Prior to 1.4.0 only link-local scope is supported; devices will self-assign link-local addresses and include them in MDNS/DNS-SD. With 1.4.0 devices will attempt to obtain a public address using the Neighbour Discovery Protocol. If successful, this address can then be used to reach a Shelly device on the network, and device will include it in MDNS host advertisements.
  • Incoming link-local IPv6 connections are supported, yet at present, devices will not attempt to use IPv6 for outbound connections. Outgoing connections to DNS hostnames continue to be IPv4 only.
