Hello Cristina,
dhcpv6 does not match on MAC address. You should match on DUID. You can find
the correct DUID for the client in the leases file.
So the reservation should look like this:
{"hostname": “XXXXX”,”duid": “00:01:00:.....:XX:YY:ZZ:AA:00:0o”,”ip-addresses":
["2001:760:422c:35::XYZ”] }
If the client is a windows machine, it would probably must also match on iaid
parameter.
