Description Markus Gothe 2019-09-09 11:36:12 UTC 
From the RFC: "A client MUST include an Elapsed Time option in messages to indicate how long the client has been trying to complete a DHCP message exchange."

and it seems to be unable to get a correct lease from certain embedded DHCPv6 servers, whereas the WIDE DHCPv6 does comply and gets a lease.

What are those "certain embedded DHCPv6 servers"? Name, version?
Comment 2 Markus Gothe 2019-09-12 10:59:04 UTC 
It's embedded in the Sierra Aircard modems, however it did seem the issue was with DUID type 1 (it wanted DUID type 3). But I also observed this behavior.
