Nem wallet address?

Nem wallet address ???
The example address would look like this: NBZMQO7ZPBYNBDUR7F75MAKA2S3DHDCIFG775N3D

What is this address? >>> TDWTRGT6GVWCV7GRWFNI45S53PGOJBKNUF3GE6PB ???
Can someone explain to me, thanks a lot!

The one that starts with a ā€˜N’ is a mainnet address.

This one is for testnet, it should only be used for testing, its worthless.
