Details - This is a request for a common DHCP function found in other software. It would be nice for an odhcpd general option to enable it to fill in unnamed leases. DHCPv4 use the MAC as in unknown-010203040506 and DHCPv6 use the last 64 bits of the DUID as in unknown-0102030405060708. This can be used to figure out which device has failed to send its host name. This is a common problem with DHCPv6. This is a common problem for smart TV or cameras. Consider logs from a device other than the DHCP serving router. Consider where IT may not want to static assign 100's of host names for display devices over a large work site or campus. Security logs and DHCP logs on a distributed network can then be reconciled a-synchronously, off line, or only when an investigation is required.
