iop.org Overview

Description of iop.org

iop.org appears to be the official website of the Institute of Physics, a long-established organization associated with physics education, research, publishing, and professional support. The domain name, age, and classification data suggest it serves as an institutional web presence for educational and reference-related content rather than a personal or temporary project.

Based on the available categories, the site appears to focus on education, reference materials, and broader business or organizational information connected to the physics community. A domain registered in 1994 and ranked within the more-visited sites globally is consistent with an established nonprofit, academic, or professional institution operating a mature public-facing website.

Safety Assessment for iop.org

At the time of this scan, no security engines reported detections for iop.org, with 0 out of 91 engines flagging the domain. Malware scanning also indicated no flagged files, and the checked external links, referenced domains, and iframe elements did not show malicious indicators in the available results. In addition, major threat-database and blacklist checks were reported as clean at the time of review.

The domain's long registration history, strong traffic rank, and consistent education-related categorization across multiple web-classification providers all support the impression of an established institutional website. While no point-in-time scan can guarantee future behavior, the available evidence does not show signs commonly associated with phishing, malware delivery, or deceptive storefront activity.

Based on available scan data, no significant threats were detected at the time of this scan.

Technical Description

The site uses a valid SSL/TLS certificate issued by Let's Encrypt, with expiry listed as 2026-07-27. It appears to be served through Cloudflare infrastructure, while hosting is associated with Pantheon and the resolved server IP is 23.185.0.4 in San Francisco, United States. The domain uses Amazon Registrar nameservers across multiple AWS DNS endpoints.

DNSSEC is reported as unsigned, which is not uncommon but means DNS responses may not benefit from DNSSEC validation. No immediate technical security concerns were evident from the provided scan data beyond that general observation.
