Ireland will play Wales and Fiji in the Aviva in a one-off Eight Nations tournament in November.
The tournament, which will go ahead after this year's remaining Six Nations games are played, will also see Ireland venture to Twickenham to play England.
The second pool of the tournament includes Scotland, France, Italy and Japan.
The games will be run off in four weeks beginning November 14th with the winners of each pool playing in the final, scheduled for December 5th.
Second, third and fourth placed teams in each pool will also face off.
The number of spectators permitted to attend the matches in the Aviva is not yet known, but if the Government implement a one-meter social distancing requirement, 18,000 people will be allowed to attend, as reported in The Irish Times.
However, for the match against England, RFU chief executive Bill Sweeney has said he hopes up to 40,000 people will be permitted to attend the matches in Twickenham pending the UK Government's approval.
Regardless of where Ireland place, their final match beyond the pool stages will also be played in Dublin.
