DNS stuck??

I recently changed DNS hosting on 2 of our domains. 1 is fine but the other is still resolving to a park page with eNom. It’sMonday evening and I made the change on Friday afternoon. The kicker is, this only happens from MY HOME. Could my ISP’s DNS be incredibly slow to update?? I’ve tried flushing my cache etc. but no luck.

Any info would be great!

Thanks.
