Website Overview

Several search or sharing settings need attention. Together they may make snippets, preview images or preferred URLs less consistent across platforms.

Domain and Registration

Unknown

DNS and Email

Nameservers are provided by umich.edu, indicating managed DNS hosting. MX records point to the umich.edu email service. No CNAME was found; the observed records resolve directly to addresses. SPF and DMARC are configured. DKIM status is unknown. TXT records include verification markers for Google, Apple, Atlassian, Meta. Such markers may also remain after a service stops being used.

TLS and Certificates

The public key uses EC with 256 bits. The server supplied a complete certificate chain. No organization name is present in the certificate; the available fields are consistent with domain validation. The certificate was issued by Let's Encrypt, commonly associated with automated certificate services. The certificate's total validity is about 89 days, consistent with a short renewal cycle.

HTTP and Browser Security

The response lacks these common security headers: CSP, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, clickjacking protection. No X-Powered-By header was found, reducing one common source of backend fingerprinting information. No obvious internal addresses or debug information were found in the headers. The Server header contains the custom value Netlify. No explicit CDN or WAF marker was found in the response headers.

Technology Stack Analysis

The public page identifies Drupal, Google Tag Manager, Netlify without precise versions, leaving fewer clues for version-specific scanning.

Search and Social Sharing

The meta description has 317 characters and may be shortened in search results. The canonical URL points to another host: https://www.lib.umich.edu/. Search engines may consolidate indexing signals there. The title has 30 characters, within a common display range. The observed directives allow indexing and link following. No Generator meta tag is publicly exposed.
