OpenWrt's dnsmasq will serve PTR records corresponding to DHCP leases, so you can use reverse DNS lookups. Use something like: dig -x ip_address_here For me

OpenWrt's dnsmasq will serve PTR records corresponding to DHCP leases, so you can use reverse DNS lookups. Use something like: dig -x ip_address_here For me it would be ideal if the prometheus exporter would expose the actual DHCP leases, but it doesn't seem to by default.
