Sweet DNS

When i go to command prompt and type in ipconfig/ all it shws everything like my dns servers but it shows three of them and i dont know which are my primary and secondary?

I have a linksys router, and i’m trying to figure out what my primary and secondary DNS are so i can hook up my PS3 online. Thanks!
