Ireland's home games against Wales, Scotland and Italy at the Aviva Stadium will be packed to the rafters as the IRFU announce that every ticket for the games have been snapped up.
Ireland's opening fixture of the Championship is against Scotland at the Aviva Stadium on Sunday, February 2.
Ireland's final home match of the tournament sees Italy line out at the Aviva Stadium on Saturday, March 8.
Padraig Power, Director of Commercial and Marketing at the IRFU, commented: "Following the scintillating performance against New Zealand, Ireland fans have been looking forward to the forthcoming RBS 6 Nations with huge anticipation.
"The Irish fans turned the Aviva Stadium into a cauldron of noise in November and with three sell-out home games the atmosphere in the stadium will be electric."
The visiting Unions are expected to take their full allocation of Aviva Stadium tickets. Should any tickets be returned to the IRFU they will be released on general sale.
