Every home in Ireland should be able to get fibre broadband by 2028.
National Broadband Ireland says it believes an assessment will be carried out, after locations included in the National Broadband Plan are connected.
It says it would help to ensure those areas excluded from the plan would be connected to fibre within five years.
Locations which aren't part of the National Broadband Plan, include parts of North Dublin and Athlone.
NBI Chief Executive, Peter Hendrick, says fast speed internet should be available to the entire country by 2028:
"If there are homes that are going to be left behind, there will obviously be a plan to bring everybody to a gigabit per second."
"Ours is to address the worst affected, that there is no commercial operator going to build in those areas."
"So I do believe, maybe by '26, that there'll be an assessment of all of those homes."
