Ireland will be getting ready to face a number of familiar foes as they hope to qualify for the 2020 European Championships.
In total - for those planning on travelling to all four countries - return trips will clock up in the region of 16,000km.
Here we look at the countries, most likely destinations for away matches, and how supporters might get there.
Three of the destinations are expected to entail at least two flights each way.
Supporters will have begun booking flights and accommodation when the fixtures were decided late last night.
And the search online for deals will continue today.
:: Capital: Gibraltar
:: Population: 34,571
:: World ranking: 194
:: Fixture date: March 23
First up is another trek for the loyal band of supporters.
Skyscanner shows that a stop-off in London is the best bet, but it will still take at least five hours to get there.
The last time Ireland travelled away for a match with Gibraltar, the game was held in Faro, Portugal.
It's understood that this could happen again, so a direct flight with Ryanair that takes three hours would be a welcome one for supporters
:: Capital: Copenhagen
:: Population: 5.77 million
:: World ranking: 10
:: Fixture date: June 7
An adversary of recent years for Ireland, where Martin O'Neill's team had lost twice at home and drawn twice away.
It's anticipated that Ireland will travel to Copenhagen this time, as they did for the World Cup play-off last year.
However, last month's clash between the teams was held in Aarhus.
Copenhagen is probably the simplest of trips for Irish supporters, though it's going to be pretty expensive once you arrive there.
Both Ryanair and Norwegian Airlines do direct flights to Copenhagen from Ireland.
:: Capital: Tbilisi
:: Population: 3.7 million
:: World ranking: 89
:: Fixture date: October 12
It is the fifth trip to Georgia in the last 15 years and Ireland fans are well used to the efforts needed to get there.
This is sure to be the most dreaded of trips for Irish supporters and is another where more than one flight will be needed to get there.
According to Skyscanner, the quickest route to Georgia at the moment would be to fly to Istanbul first and then onto Tbilisi.
However, even at that, it will mean eight hours to get there.
The distance between Dublin and Tbilisi is 5,000km.
:: Capital: Bern
:: Population: 8.4 million
:: World ranking: 8
:: Fixture date: October 15
Despite Bern being the capital, it's expected that Ireland will take on the Swiss in Basel at the 38,500 seater St Jacob-Park.
There are no direct flights from Dublin to Basel so it could take supporters up to four hours to make it to here in what will be close to a 3,000km round-trip.
