I guess you can pick an empty or safe spot from here[1] and send patches to major DHCP server implementations, feels like option 81 "Client FQDN" is already close to that though.
Also do keep in mind that an OS instance can have multiple Ethernet interfaces, and that each interface can have multiple IPs, and that not all DHCP gives out private addresses(University Wi-Fi gave me 133.xx back in the days ... behind NAT!), and that double NAT exists.
