Class 4 or 5 Sim?

Noticed this small but useful piece of information on the LL blog today:

"If you look at Help:About Second Life, you will find a line that tells you the host on which your region is running. That will say something like sim1234.agni.lindenlab.com. If the number after “sim” is less than 2133, the region you are in is a class 4 region..."

So, here is a simple method of finding out what kind of server your land is on.

Btw: The Big Mushamush sim is on sim5634.agni.lindenlab.com, so its Class 5. Nice to know.
