Nothing in your post indicates why you think that's incorrect; 
dnsmasq IS a DNS server.  Typically that's what you want, for all 
local DHCP clients to use dnsmasq as DNS server.  The point being: to 
have local name resolution and to have one central cache for external 
names.

Yes, there is an option you can use in dnsmasq.conf to change the
nameserver[s] given to DHCP clients, but why do you want that?  See 
the dnsmasq(8) manual for details.
