Can i allow all IP addresses to my database?

I host a script on heroku but they dont provide their IP so i need to allow all on digitalocean.

I tried which changed to “AllIPv4” when i entered it but when i click save, it gives me the error: “The prefix (the number following the slash) cannot be less than 10.”.

Any help is appreciated!


You add IP addresses in the DO dashboard so i’m not sure if doing this would work.

If you is using MySQL you can use % to represent “all”

GRANT ALL ON mydb.* TO myuser@‘%’ IDENTIFIED BY ‘my_password’;

“The prefix (the number following the slash) cannot be less than 10.”

Looks like a validation error from ufw

I think that if you don’t specify any IP addresses and leave the allow list empty it would mean that the traffic to the database cluster would be allowed for everyone.
