Database list by Servers

Hello,
We have 100+ servers/Instances and each servers Instance contains few databases and i would like to get the all database list by each server/instance.
Instead of running query on each sever to get the database list, can i get database list by servers?
Ex.
Server1
DB1
DB2
DB3
Server2 DB1
DB2
DB3
DB4

Thanks for your help!

Something like this is your best approach.

Powershell to crawl your network but it would require some setup.

Thanks.
