Ireland will play their first home Davis Cup tie in nine years when they face highly-ranked Austria at the University of Limerick Arena in February.
Former World No 3 Dominic Thiem is likely to be in the visitors' line up for the play-off match while the other players expected to travel, Jurij Rodionov (111) and Dennis Novak (166), will also present a stiff challenge to the hosts.
There will be two singles ties on Saturday 3 February with a doubles and two further singles being played on Sunday. The winning team will progress to the second-tier World Group I.
Ireland have risen from Group IV to Group II since 2019 and are now in the Group I playoffs for a second successive year after wins over Georgia, Barbados and, most recently, El Salvador in September. They were beaten 4-0 by Peru in this year's play-off.
Austria are ranked 27th in the world, 23 places higher than Ireland.
Irish captain Conor Niland said: "The players and I are incredibly excited to have the opportunity to bring Davis Cup tennis back to Ireland, and particularly in the town where I grew up and learned my own tennis.
"Of course the Austrians are very strong, and I can promise everyone who comes that they will be seeing truly world-class players up close and in person. But while we’ll face a stiff test, we’ll rise to the challenge, and I know you can never discount home advantage, especially when the Irish Tennis public get behind their players".
Tennis Ireland CEO Kevin Quinn said "This will be an unmissable weekend on the tennis calendar. The arena in UL is a new venue for indoor professional tennis and its location, size and impressive facilities will allow us attract the largest possible audience.
"The Davis Cup was played in Limerick once before, back in 1989, when we defeated Senegal 4-1. We’re hoping that win will inspire this team, and that the exciting event will attract general sports fans as well as all our traditional tennis fans and the many new ones who recently discovered our wonderful sport."
