Many home broadband routers include DNS proxies.  Computers on the LAN 
can point their resolvers to the router, and it will relay the queries 
to the DNS servers in its configuration (usually learned from the ISP 
via DHCP, but may be statically configured instead).  It doesn't do any 
caching, and just relays the queries and responses without modification, 
except for doing NAT.
