We _do_ do some packet capturing and DPI sometimes when we’re trying to troubleshoot certain issues.  We _always_ log PII as the meeting goes on (like IPs and MACs).  What we don’t do is retain this data beyond its useful lifetime and definitely not beyond the meeting time (without some anonymization).

Thanks.

That sounds good.  Sets some context while being flexible.

In general, we need to provide compute infrastructure to support remote participation, and we need to provide a way to scalable address client hosts and provide name resolution.  For example, we may drop DHCPv6 at some point as RDNSS is fairly well-supported in RAs.

The best I could come up with is “…MUST be able to dynamically address clients”, which I admit is not good.  Maybe we can live with the DHCPv4 text as it is now and change DHCPv6 to MAY.
