Does anyone have this channel? I don't know if it is a new channel but they show nicktoons all day including the old nicktoons that you can't get on Nickelodeon anymore such as Rocko's Modern Life and Ahhh Real Monsters.

Yes,
NickToons TV is brand new, and is currently offered on many Digital Cable systems. They air current and past Nickelodeon Nick Toons :), which is quite obvious by the name! It is very similiar to Toon Disney.
