Setting DNS in router

i want to know if dns setting is needed in router also ? well i have not configured it in any pc....i have only updated in dsl modem

i did this due to reason that secondary dns is changing continuously since yesterday. and also i am not getting speed at the moment :(

i have heard quite a bit of open dns .... can any one tell me where to set open dns ? at modem or router or every single pc ?

keep the settings as they are.
