You don't need to use dhcp-ignore to achieve what you're trying to do, 
the "net:phsalt" in the dhcp-range is enough to ensure that the range 
only gets used for the hosts which set the phsalt tag.

However, I'm not sure _why_ the configuration you have is behaving as it 
does. Please could you set --log-dhcp and send me the information that 
dnsmasq logs during these DHCP transactions?

Cheers,

Simon.
