Ripping is not a good term to use. Most people associate it with thievery. One assumes you are converting a cd of yours to say mp3 so you can play on your pc.
You really did not give a lot of details on what software you are using. In most cases, you have to allow the software to access the internet (by the player settings and the pc being online) so it can retrieve track info from freedb, cddb or windowsmedia.com's db.
