How to delete unnecessary up to a certain character and go to the next line in notepad ++?

Question

Notepad++

Need a regular expression to remove characters. The bottom line is this
Line type
text (+ possibly numbers): text (+ possibly numbers): IP (only numbers here): text (+ possibly numbers)
And now you need to delete everything up to the first : and go to the next line. For the expression .+(17 ) blows everything down to the last colon. That is to delete everything only up to the first colon
Thank you!
