Autechre, Boards of Canada, The Flashbulb, Squarepusher and uZiq all come under the (awfully named) IDM subgenre.
They also tend to hold a steep barrier to entry and they're the type of thing you either love or don't see the point in.
Electronic music is a massively unspecific term to use, though - electronic covers anything from your general brostep tracks to classic house, electro swing, glitch hop and e everything in between.
If you enjoyed Netsky you'll probably enjoy many of the poppier drum n bass tracks and possibly liquid DnB.
DnB Chart favourites in the last year that you might like/recognize could be Rudimental, Nero and Chase & Status, although the latter two tend to have harsher-sounding songs that fit better to live gig settings.
