Hi,

This is normal.  You can log option 82 data in Kea using the forensic
logging hook: https://kea.readthedocs.io/en/kea-3.0.2/arm/hooks.html#libdhcp-legal-log-so-forensic-logging.
If you spend a lot of time, you could probably create logs that look
very much like what you were getting with your conditional log from
ISC DHCP.

Thank you,
Darren Ankney
