How do you specify IP ranges when creating a firewall rule?

When creating a firewall rule in Google Cloud, you specify IP ranges by defining source IP ranges in the rule configuration. This approach allows you to granularly control which IP addresses are permitted or denied access based on your security requirements. The source IP ranges can be specified as single IP addresses, CIDR notation (for example, 192.168.1.0/24), or as a specific range. This flexibility is crucial for setting up rules that align with your network's security posture, enabling you to manage inbound and outbound traffic effectively.

Utilizing this method ensures you have precise control over who can access your resources, facilitating security based on the needs of your organization. By selecting specific ranges, you can tailor your firewall rules to only allow traffic from known, trusted sources, enhancing the overall security of your network environment.
