Registering Self-generated IPv6 Addresses using DHCPv6 (Jen Linkova)
- Jen presented slides
-
Bernie brought up (in relation to transaction IDs) that they are
useful for the client in some situations- Matching up reply that comes for a given request
- Jen said draft does clarify how client handles replies (matching
transaction IDs) - Bernie brought up that it's not terribly useful for Servers, but
will examine draft and give further comments later
-
Tim asked if there were any known implementations
- Lorenzo said they plan to put a client implementation together
for this, will update the list when something is available
- Lorenzo said they plan to put a client implementation together
-
Eric brought up the topic of a hackathon for this
- Lorenzo said they can definitely come up with a basic proof of
concept before next meeting
- Lorenzo said they can definitely come up with a basic proof of
-
Some further discussion on security considerations
- Jen says spoofing clients might be tricky, so that might not be
a path to go down now -
Tim C. Also security implications of including DNS information
in these messages (verifying client's hostname in registration?)- Lorenzo clarifies that the direction was "people could do
this", but not a recommendation/requirement one way or
another
- Lorenzo clarifies that the direction was "people could do
-
More discussion on MAY/SHOULD language for accepting(?) DNS info
from clients
- Jen says spoofing clients might be tricky, so that might not be
-
Bernie brought up using ISC Kea as a baseline implementation that

- Some mention from Bernie during this on RFCs that describe
operational suggestions
- Some mention from Bernie during this on RFCs that describe
-
Arran brought up RFC 9096 in relation to the issue where a CPE may
release PD prematurely- Suggested to re-use text from that RFC for this in 8415
- Tim talked about other drafts related to clients that do PD, but
will it be widely deployed? - Bernie suggested being careful about adding more text rather
than referring to other informational/operational RFCs - More discussion to happen on list
-
Arran also wonders why unicast option was deprecated. Could be a
situation where a relay is involved and we may want to specify an
upstream server- Bernie gave some context that server unicast options may not be
widely used, and using it could cause other operational concerns - Arran requested more discussion for mechanisms about unicasting
packets
- Bernie gave some context that server unicast options may not be
-
Eric asks about whether new documents that provide operational
guidelines are informative or normative
Next Steps and Wrap Up
- Lorenzo requesting that folks take a look at v6ops draft for
signaling PD availability on LAN
