Here's what we know:
* Apparition points are a secret network of locations where wizards can apparate. It's assumed that these points are well-known amongst wizards and witches, similar to how Muggles use landmarks to navigate.
* Dumbledore is a powerful wizard. He is known for his extensive knowledge of magic and his ability to perform complex and difficult spells. It's safe to assume that he's very familiar with the use of apparition points.
* He travels widely in the books. He visits various locations, including Hogwarts, the Ministry of Magic, and even Grimmauld Place. He likely uses apparition points to quickly and efficiently travel between these locations.
However, the books focus more on Harry's perspective and don't delve into the specifics of Dumbledore's travel methods.
Here are some instances where Dumbledore's use of apparition points can be inferred:
* In Order of the Phoenix: Dumbledore travels to the Ministry of Magic to confront Fudge about Harry's truth. It's likely that he uses apparition points for this journey.
* In Half-Blood Prince: Dumbledore is shown frequently traveling to various locations for his research on Voldemort's past. He might be using apparition points for these trips.
* In Deathly Hallows: Dumbledore travels to various places with Harry and Ron before his death. Again, it's safe to assume he uses apparition points to move quickly.
While the books don't specify Dumbledore's use of apparition points, it's highly likely that he utilizes them to navigate the wizarding world efficiently.
