Hi:

As a follow-up from the IETF-93 (Prague) DHC WG session and the DHCPv6 bis Issues (see https://www.ietf.org/proceedings/93/slides/slides-93-dhc-7.pdf):

For slide #4, Lifetime Hints (#148), we want to confirm the WG consensus to adopt the proposal to DROP lifetime hints stands:

Proposal: Drop lifetime hints; servers SHOULD/MUST ignore any supplied lifetimes (clients SHOULD NOT send - i.e. send 0)

Please respond if you do not agree with this proposal and please indicate why.

The rationale for this proposal is that clients often get the hint wrong (they will use what they previously got for a lifetime or perhaps even just the remaining lifetime - which can result in shorter and shorter lifetimes) which makes use of this information by the server problematic. If a client wants a shorter lieftime, it is always free to release it earlier.
