Noel and Liam Gallagher announced on Tuesday they are reuniting for a 17-gig tour, including two nights in Croke Park next August.
Newstalk Tech Correspondent Jess Kelly has some top advice for people hoping to Definitely Maybe get tickets.
"Set up your Ticketmaster account - if you've never bought anything from Ticketmaster, if you haven't logged in for a while - go in and make sure that you have your password and be logged in beforehand," she said.
"I'd also recommend, if possible, to store your card in your account so that you have all the details to hand.
"[You should] be patient: the demand for these tickets will be incredibly high."
Jess said some people will be trying to buy across multiple devices.
"I know that some people normally have multiple tabs open on a browser - that is one way to do it" she said.
"What I'd recommend you do is have a laptop and a phone [and] have seperate devices if you can."
For those in the queue for tickets, Jess said people need to just wait.
"Once you're in the queue do not refresh the page because that'll put you to the back of the queue," she said.
"So just be prepared: have your account details ready, store your card into your phone and hopefully fingers crossed we'll all get tickets".
Tickets for the Dublin gigs are on sale an hour before those in the UK.
