Hi.
I am trying to install Metabase on Ubuntu.

I started Metabase.jar (from metabase.com) with following command.

java -DMB_PASSWORD_COMPLEXITY=normal -DMB_PASSWORD_LENGTH=10 -DMB_JETTY_HOST=0.0.0.0 -DMB_JETTY_PORT=3000 -DMB_DB_TYPE=mysql -DMB_DB_DBNAME=metabase -DMB_DB_PORT=3306 -DMB_DB_USER=<my_db_user> -DMB_DB_PASS=<my_db_pwd> -DMB_DB_HOST=localhost -DMB_EMOJI_IN_LOGS=true -jar metabase_lts.jar

Then I check port usage with this command
sudo lsof -i -P -n | grep LISTEN

What I gonna ask is ...

Metabase is running at IPv6.
I am not sure if it is ok.

I gonna access my metabase with IPv4 address or DNS.
Should Metabase run at IPv4 ?

Sorry for bothering you with this question.

Looking forward to your kind consideration.

Best regards.
