How to Whitelist an IP Address in PostgreSQL Server?
A guide to whitelist Superjoin’s IP address in your PostgreSQL server for access.
Superjoin’s IP Address is 34.100.193.122. Whitelist this IP Address in your database and allow TCP/IP connection from this IP in your firewall.
What is “Whitelisting”?
Think of your database like a private party. The “whitelist” is your guest list. Only the IP addresses (unique identifiers for computers on the internet) on this list can “enter the party,” i.e., connect to your database. IPs not on the list will receive the metaphorical “you’re not on the list” and cannot connect.
