Hi All,

The grammar for candidate-attribute in ICE SDP says:

   candidate-attribute   = "candidate" ":" foundation SP component-id SP
                           transport SP
                           priority SP
                           connection-address SP     ;from RFC 4566
<https://tools.ietf.org/html/rfc4566>
                           port         ;port from RFC 4566
<https://tools.ietf.org/html/rfc4566>
                           SP cand-type
                           [SP rel-addr]
                           [SP rel-port]
                           *(SP extension-att-name SP
                                extension-att-value)


Is there a registry for ICE extension-att-name? How does one looks up
where extension-att-name
is defined, what it means, and how it is used? Are there any rules
associated with ICE candidate extensions?

As far as I know there are two extension attributes that are commonly used:
"generation" and "network" but I am not sure where these values and their
usage are defined.

Regards,
