My router has two VLANs: one "lan" (ports 1-3) and one "guest" (port 4); connected to port 1, I've got a Samknows whitebox. The local wired clients are connected to this secondary switch.
Now, I don't need to access it directly and all is working fine, I'm just confused by the "broken" prefix in the hostname: what could it be? The box can be pinged using the IPV6 address from the "lan" and does not respond when pinged on the "guest" address, which is to be expected since port 1 is untagged and only belongs to "lan".
If you click the image to enlarge it, you will see that both leases have "broken" as hostname prefix, the missing line in the middle refers to a different host.
Only difference is the subnet prefix in the address.
This is done by odhcpd when the received dhcpv6 client hostname tag is invalid, means containing illegal characters, wrong series of dots, overlong labels etc.
When such a hostname is detected, the prefix broken\x20 is prepended in the lease file to denote such cases and the name is not added to the autogenerated hosts file.
