Note Drupal will prevent you from banning your own IP address.

2. Beside an IP address, click Delete.

Remove a ban with Drush

These commands show all entries, removes the ban on a specific IP, and removes all bans using Drush.

drush sql:query "SELECT * from ban_ip;"
drush sql:query "DELETE FROM ban_ip WHERE ip='119.80.1.6';"
drush sql:query "TRUNCATE ban_ip;"

Recommended modules/libraries

For more advanced features and sophisticated levels of IP based protection, it is also worth considering system installed alternatives such as fail2ban.
