Guys - What is the use of DHCP-Authoritative? switch just was wondering what are the effects in DD-WRT. Tried searching on net and there is no clear explanation for this anywhere. (Even out of DD-WRT world)
-K, --dhcp-authoritative
Should be set when dnsmasq is definitely the only DHCP server on a network. It changes the behaviour from strict RFC compliance so that DHCP requests on unknown leases from unknown hosts are not ignored. This allows new hosts to get a lease without a tedious timeout under all circumstances. It also allows dnsmasq to rebuild its lease database without each client needing to reacquire a lease, if the database is lost.
A better explanation of what it means is on the ISC DHCP page.
