HITC Sport also understands from sources close to the situation that Southend's fellow Essex based side Colchester United are also monitoring the youngster.
Scott, 19, began his career with Charlton Athletic where he spent six years in their academy before joining Southend's under-16 side.
He is still to make his first team debut for Southend, but has featured for their under-21 side, and was handed a new deal by the club last year, the South Essex Echo reported.
The trio of clubs are monitoring his development, which is a positive sign for the strides he is making.
Southend United are currently eighth in League One, just outside the play-off spots, while interested side Colchester United are bottom of the division.
Ipswich are ninth in the Championship, still hoping to mount a promotion push to the Premier League via the play-offs, while Preston are three points and one place behind in 10th.
Scott's pace and dribbling ability can be seen in this goal netted for Southend's youth side side back in 2013. The goal is the first in this League football Education compilation video.
