Ironic, really, since IP addresses for every streetlight was one of
the favourite examples in the IPng days.

Let me quote from RFC 1673 "Electric Power Research Institute Comments on IPng",
authored by

 "2. Basic Requirements.

      - Scaleability
        The addressing scheme must have essentially an unlimited address
        space to encompass an arbitrarily large number of information
        objects.  Specifically it must solve the fundamental limitations
        of 32 bit formats, a format for 20 octets and above is considered
        suitable."

(The document was biased towards OSI addressing.)
