The opening weekend on February 4/5 - which already sees Wales and England make history by starting the Championship on a Friday night - are a reverse of 2010's first round games with Ireland and Scotland travelling to Italy and France respectively.
Ireland's first match back at Landsdowne Road after four years at Croke Park is at home to Les Bleus the following weekend.
The tournament takes on extra significance with the 2011 World Cup just months away and David Pickering, Chairman of the Six Nations Council, said: "The RBS 6 Nations Championship remains the envy of the rugby world, a tournament played with pride and passion and drenched in history and tradition".
