Hello Darren, Thank you very much for your reply and correcting this issue.
1) I was aware of the 2.6 requirement and re-installed everything from scratch a little over a month ago. [root@dhcp-test ~]# kea-dhcp4 -v 2.6.1 [root@dhcp-test ~]# kea-dhcp6 -v 2.6.1 2) However, I have been following this link: https://kea.readthedocs.io/en/kea-2.6.0/arm/hooks.html#bulk-leasequery-configuration Which indicated to me that the option “extended-info-tables-enabled” would have provided the same functionality. However, as you pointed out, there was no relay ID in the lease table. I have since added the global parameter "store-extended-info" as you suggested, and I now see the JSON now at the end of each memfile lease. I hope this helps anyone trying to accomplish the same thing.

Are you using Kea 2.6.1 ? I think the relay-id method was not available before 2.6 2. Have you globally set "store-extended-info": true ? (see: https://kea.readthedocs.io/en/kea-2.6.1/arm/dhcp6-srv.html#storing-extended-lease-information) as this is required as well. It doesn't appear so from the lease you pasted as I don't see any data in the "user-context" field.
