AI Summary

The website ip138.com is a well-established Chinese online platform providing a variety of data lookup services including IP address location, mobile phone number attribution, postal code and area code queries, and ID card verification. Founded in 2004 and operated by 厦门市漫游科技有限公司, it serves a broad general audience primarily in China. The site offers a comprehensive suite of tools and informational services, positioning itself as a trusted resource in the technology and data query sector. The business model appears to be based on free access to information, likely monetized through advertising and affiliate partnerships. Technically, the site uses standard web technologies including HTML5, CSS, and JavaScript, with integration of Baidu analytics and link submission scripts for traffic monitoring and SEO. The domain is hosted by a reputable registrar and uses HTTPS, ensuring secure communications. The site is mobile-optimized and provides a good user experience with clear navigation and a consistent brand presence. However, there is room for improvement in accessibility and the implementation of modern security headers. From a security perspective, the site enforces HTTPS but lacks DNSSEC and explicit security headers such as Content-Security-Policy or X-Frame-Options. No privacy or cookie policies are present, which is a compliance gap especially under GDPR-like regulations. There is no visible incident response or vulnerability disclosure information. The site does not appear to be blocked by any WAF or security challenge, and no adult or questionable content is detected, making it safe for general audiences. Overall, ip138.com is a credible and functional information service platform with a solid business foundation and moderate technical maturity. Strategic improvements in privacy compliance, security headers, and transparency around security policies would enhance its trustworthiness and compliance posture.
