method: probed
source: live DNS/TLS/HTTP probes of every host published in apis.yml
note: >-
  Rex publishes no OpenAPI and no API host, so the hosts probed here are the
  public web properties named in apis.yml — the marketing site, the internet
  booking engine, manage-my-booking, the EveryMundo/AirTRFX fare-page host and
  the Rex Flyer loyalty site. Absence of a record (no CAA, no HSTS, no DNSSEC)
  is recorded as measured, not inferred.
hosts:
- host: www.rex.com.au
  https: true
  tls_version: TLSv1.3
  cert_expires: Feb 28 03:38:34 2027 GMT
  hsts: false
- host: ibe2.rex.com.au
  https: true
  tls_version: TLSv1.3
  hsts: true
  hsts_max_age: 2592000
  note: Internet booking engine. Root returned HTTP 500 to a HEAD request at probe time.
- host: mbe.rex.com.au
  https: true
  tls_version: TLSv1.3
  hsts: true
  hsts_max_age: 2592000
  note: Manage My Booking. HTTP 200.
- host: flights.rex.com.au
  https: true
  tls_version: TLSv1.3
  hsts: true
  hsts_max_age: 31536000
  hsts_include_subdomains: true
  hsts_preload: true
  note: >-
    EveryMundo / AirTRFX fare-marketing pages. HTTP/2, returned 405 to a HEAD
    request. Strongest transport posture of any Rex host — and it is a vendor's
    stack, not Rex's own.
- host: www.rexflyer.com.au
  https: true
  tls_version: TLSv1.2
  hsts: false
  note: Rex Flyer loyalty. Only host still negotiating TLS 1.2 rather than 1.3.
domains:
- domain: rex.com.au
  dnssec: false
  caa: []
  spf: true
  dmarc: true
  dmarc_policy: none
- domain: rexflyer.com.au
  dnssec: false
  caa: []
  spf: false
  dmarc: false
  note: >-
    No TXT records at all at the apex — so no SPF — and no _dmarc record. The
    loyalty domain publishes no email authentication of any kind.
findings:
- HSTS is absent on the primary www host and on the loyalty host.
- No CAA records on either registrable domain.
- No DNSSEC on either registrable domain.
- rex.com.au publishes DMARC but at p=none (monitor only, no enforcement).
- rexflyer.com.au publishes neither SPF nor DMARC.
