True, of course! The host has to find the DNS server first before it can check for duplicate IPs. That's just basic networking 101.

False. Wouldn't the host need to know the IP address of the DNS server to send an ARP query? Sounds like a chicken and egg problem to me.

True, the host can send ARP queries for the MAC address of the local DNS server before checking for duplicate IPs. Why not just ask the DNS server directly?
