ip-addr.info is a lightweight public IP lookup service designed for developers and operations scenarios. The page directly displays the IP address currently used by the visitor, and it explicitly supports terminal access via cURL, returning the IP used by the current request. For users who need to quickly confirm an outbound address, troubleshoot network connectivity, or read a public IP from a script, it is a typical small, practical developer tool.
Based on the captured page content, the service’s core functionality is highly focused: returning the IP address of the current request. It supports specifying the IP version through subdomains, using the “ipv4” or “ipv6” subdomain to query the corresponding protocol stack, which is useful for dual-stack network testing. In addition, the service supports HTTP GET requests and can return a JSON object by setting Accept: application/json in the request header, for example: curl -H "Accept: application/json" https://ip-addr.info. This means it is not only suitable for manual checking in the terminal, but also easy to embed into Shell scripts, CI/CD pipelines, monitoring probes, or backend programs.
The page does not provide any information about pricing, accounts, authentication, rate limits, or commercial plans, so it is not possible to determine whether it is completely free, whether call frequency limits exist, or whether a paid SLA is available. The page also does not state whether the project is open source or whether a self-hosted version is provided.
Its advantages are simplicity, a low learning curve, cURL friendliness, and support for IPv4/IPv6 and JSON responses, meeting most automation needs for “checking the current IP.” The drawbacks are also clear: documentation is limited, with no error codes, response field descriptions, privacy policy, stability commitment, service status page, or SDK information. If used as a critical dependency in a production system, its availability and fallback options should be carefully evaluated.
It is suitable for developers, operations engineers, network troubleshooting personnel, and users who need to quickly obtain a public outbound IP in scripts. It is less suitable as an enterprise-grade IP intelligence or geolocation service with a strong SLA.
The captured page content does not provide information about access from mainland China, so it is not possible to determine whether direct access is available. Actual testing is recommended before using it in a domestic production environment.
