DHCP
Dynamic Host Configuration Protocol, used to automatically assign IP addresses and related network configuration parameters to network devices.
Timeline (last 90 days)
In OpenSense, after adding a VLAN interface, you must manually check that interface on the General tab of the DHCP settings, otherwise devices cannot obtain IP addresses.
Some tools rely on the router's DHCP lease records to work around MAC randomization, but randomized MACs can still cause the same device to be counted multiple times.
The DHCP lease table contains device hostnames and lease expiration times, which can be used to distinguish long-term online servers from temporarily connected devices.
