How far can an Enderman move in one teleport?

Question

Is there a limit to how many blocks that an Enderman can traverse (either laterally or vertically) with a single teleport? Or is their teleporting radius essentially unlimited?

Answer 1

Edit: The wiki article on Endermen was updated with the following statement:

The range in which an Enderman can teleport is 32 meters in most cases, however informal testing on superflat worlds shows they can travel much further on the Y axis.

While this is quite ambiguous, a 32 block horizontal teleport distance seems accurate from my experience with Endermen teleporting.

One fact in the behavior section of the Enderman article on the Minecraft Wiki states that:

Endermen will never give up a chase once made hostile; even when moving several hundred kilometers from them they will continue to follow until killed or distracted by exterior elements such as water or rain.

I presume this means that there is no limit to how far Enderman can teleport. However, because the Enderman would have to exist in order for it to teleport to the character, I believe that if you somehow get 128 blocks away from a hostile Enderman (causing it to despawn), the Enderman won't teleport to you. (If it somehow stays loaded in memory, it would still be able to teleport, though.)

Answer 2

I went around 130 blocks away from one hostile Enderman, and it STILL teleported to me. It is possible that it moved, but I do not think so. Anyway, I tested your theory about 32 meters, and it worked for me. However, you have to remember: leave no spaces large enough for them to teleport to.
