IP Address Inspector

Working With IP Addresses During Debugging

IP addresses are used to identify devices, servers, applications, APIs, databases, proxies, and services connected to a network. When a request fails, a firewall blocks traffic, or an allowlist does not behave as expected, checking the IP address format is often a simple first step.

This IP Address Inspector helps you validate IPv4 and IPv6 address formats and check whether an IPv4 address belongs to a private network range. It is useful for server configuration, API allowlists, VPN testing, proxy debugging, firewall rules, and cloud deployment checks.

The tool runs directly inside your browser, so you can quickly check an IP address without sending it anywhere.

How to Use the IP Address Inspector

1. Enter an IPv4 or IPv6 address into the input field.
2. Click Inspect IP.
3. Review whether the IP address format is valid.
4. Check the detected IP version and private range result.

Common Use Cases

• Checking valid IPv4 and IPv6 address formats.
• Debugging API allowlists and firewall rules.
• Inspecting private and public network addresses.
• Reviewing proxy, VPN, and server configuration values.
• Testing cloud deployment networking settings.
• Validating IP inputs before saving configuration.
• Debugging infrastructure and network access issues.
