1. SUB-OPTION 5 is not only in RENEWING state, it is also available
within DISCORVER messages.
2. i don't think that dnsmasq will do this. The programm layout does not
use remote-id or/and circuit-id for the dhcp-range selection. DNSMASQ
tags the incoming request after valid dhcp-range was found. So your tags
based on remote-id or/and circuit-id are useless.
@simon: is there a possibility to add a option like "circuit-id" to the
--dhcp-range option? So when a DISCOVER-Message with circuit-id
receives, dnsmasq knows, which dhcp-range to choose. circuit-id should
take advance over other checks.
