# What is domain resolution/reverse resolve?

Domain resolution is to reversely resolve the address to the corresponding domain name by “setting primary domain”.

In the application scenario, after setting up reverse resolution, you can directly display the .bnb domain name you set in the DApp that supports .bnb domain name display.

For example, when you log in to the DApp with your wallet address, your .bnb domain name will be displayed instead of your lengthy address.
