Hi.

ULA stands for Unique Local Address, it is an IPv6 address that is guaranteed to be unique for a device in a specified scope. For example, an ML-EID is a ULA for the mesh-local scope. ML-EID stands for Mesh-Local Endpoint Identifier. An Endpoint Identifier that is unique to that device in a Thread interface, regardless of network topology. Thread Network uses a specific category of ULAs for the purposes of mesh routing and management within the network. In the context of the Thread Network, these are called MLAs (Mesh Local Addresses)–either ML-EID (Mesh-Local Endpoint Identifier) or ML-RLOC (Mesh-Local Routing Locator)–and are identified by a ULA prefix referred to as the MLP (Mesh Local Prefix).

Best regards,

Andreas
