What It Is

AddressRegistrar is positioned as an independent domain intelligence and website trust verification tool. It can run real-time IP, SSL, WHOIS, DNS, hosting, and reputation analysis for any website, and provides an AI Trust Scoring result from 0–100. The site highlights domain checks completed “within 10 seconds” and targets SEO teams, publishers, brand safety teams, due diligence workflows, and security analysts.

Core Capabilities

In terms of protection type, it is closer to a domain reputation assessment and security due diligence tool than an active blocking product such as a gateway, EDR, or WAF. Its reports cover IP and geolocation data, identifying hosting country, city, ISP, ASN, and organization. TLS/SSL checks include issuer, validity period, certificate chain integrity, and HSTS. WHOIS data is obtained via RDAP and includes registration date, expiration date, registrar, and domain age. The AI score combines technical signals, domain age, jurisdiction, and category recognition. The page also mentions support for 7 languages, 435,166+ checks, and 99.95% API uptime.

Pricing and Deployment

Deployment is mainly through web-based online lookup. The page includes an API availability metric, but does not disclose API documentation, authentication, rate limits, or integration methods. For pricing, it clearly states free checks, no registration required, no credit card required, and no hidden quotas. However, there is no information on paid plans, enterprise editions, SLAs, or payment methods.

Pros and Cons

The main advantage is its low barrier to entry: a single query aggregates multiple types of basic domain intelligence, making it useful for quickly deciding whether an unfamiliar site is worth visiting, partnering with, or advertising on. Its use of infrastructure such as MaxMind GeoLite2, IANA RDAP Bootstrap, and the OpenSSL TLS engine also improves the explainability of its data sources. The drawbacks are the lack of disclosed compliance certifications, team background, alerting and monitoring, bulk scanning, permission management, SIEM/SOAR integrations, and other enterprise security operations capabilities. Details on the AI scoring model are limited, making it difficult to assess false positives and false negatives.

Who It’s For and Access from China

It is suitable for initial screening in SEO, content publishing, ad review, domain purchase due diligence, and security analysis scenarios. It should not be used as the sole basis for an enterprise-grade threat intelligence platform or continuous monitoring system. Its accessibility from China cannot be determined from the page content, so real-world connectivity testing is recommended. If access is limited, alternatives include VirusTotal, urlscan.io, SecurityTrails, Google Safe Browsing, or China-based options such as 微步在线 and 奇安信威胁情报中心.
