  DNS + TLS probes run directly against 4info.com and www.4info.com on 2026-09-05
  (dig for A/AAAA/CNAME/MX/TXT/CAA/DNSKEY/DS/_dmarc, curl for HTTPS).
name: 4Info
slug: 4info
summary: >-
  4info.com is a registered, actively delegated domain that is still used for EMAIL only.
  It publishes no A or AAAA record on the apex or on www, so there is no web host to probe
  for TLS, HSTS, or any HTTP surface at all. Mail is routed through Proofpoint and the
  domain carries SPF and DMARC records, which is consistent with the domain being retained
  by the acquirer (Cadent, January 2020) for mail continuity after the website was retired.

      Authoritative NOERROR with an empty answer section for A and AAAA — the zone exists
      and is delegated to AWS Route 53 (ns-219.awsdns-27.com, ns-815.awsdns-37.net,
      ns-1382.awsdns-44.org, ns-1863.awsdns-40.co.uk) but publishes no address record.

    note: >-
      p=none is monitor-only — reports are collected by Proofpoint Email Defense but no
      enforcement is requested on failing mail.

    provider: Proofpoint (pphosted.com)
findings:
- The domain is alive for mail and dead for web; there is no HTTPS endpoint to assess.
- DNSSEC is not enabled and no CAA record is published.
- SPF and DMARC are both published; DMARC is at p=none (monitoring only).
