PostgreSQL IP Restriction for Enhanced Security

I guess you need something like this in [login to view URL] host all all [login to view URL] md5 host all all [login to view URL] md5 host all all [login to view URL] md5 host all all [login to view URL] md5

Hi! How are you doing? I am an experienced in PostgreSQL database administration, network security, and server configuration with over 5 years of hands-on experience. I have successfully completed similar projects where I have configured PostgreSQL to accept connections from a limited set of IP addresses. For your project, I will review your current PostgreSQL configuration and provide a solution to restrict access to only 5 specified IP addresses. I will calculate the appropriate CIDR notation for the allowed IP addresses and update the PostgreSQL configuration files accordingly. This will ensure that your PostgreSQL database is secure and accessible only to the authorized users. Please initiate the chat for further discussions and my previous work. What is the specific CIDR notation you would like me to use for the allowed IP addresses? Additionally, do you have any specific requirements or constraints I should consider in my solution? Thank you.
