Porakas IV was the fourth planet in its star system, located in the Delta Quadrant.
In 2373, the USS Voyager visited this planet and picked up some Porakan eggs here, which Neelix later served Tuvok. (VOY: "Flashback")
This planet was only mentioned in dialogue.
According to the Star Trek: Star Charts (p. 86), this was a binary system with a pair of G-class stars. The USS Voyager contacted this system on stardate 50100.
