What is being checked

• i
  info: RadioDNS lookup name

  08890.8585.8a0.fm.radiodns.org (frequency 88.90 MHz, PI 8585, country code 8a0)

1. RadioDNS registration

• ✓
  pass: Registered

  08890.8585.8a0.fm.radiodns.org points to the station's authoritative domain: radiodns.prss.org

2. Service discovery (SRV records)

• i
  info: _radiospi._tcp.radiodns.prss.org: not published
• ✓
  pass: _radioepg._tcp.radiodns.prss.org published

  priority 10, weight 60, port 80 -> radiodns.prss.org [target is an alias of contentdepot.prss.org]
• !
  warn: SRV target radiodns.prss.org is a CNAME alias

  DNS rules (RFC 2782) say an SRV record should point at a name that has address records directly, not at an alias. Many resolvers cope, some do not.

  What to do: Give radiodns.prss.org its own A/AAAA record (or point the SRV record at the real host name).
• !
  warn: Only the older _radioepg record is published

  What to do: Add _radiospi._tcp.radiodns.prss.org on port 443 as well, so receivers that use HTTPS can find the SI file.
• i
  info: _radiovis._tcp: not published

  Slideshow/visuals (STOMP) - optional, only needed for a live slideshow service.
• i
  info: _radiopush._tcp: not published

  Slideshow/visuals (Server-Sent Events) - optional, only needed for a live slideshow service.
• i
  info: _radiovis-http._tcp: not published

  403 ms, 261,799 bytes
• ✓
  pass: Content type is application/xml
• !
  warn: SI file has no caching headers

  What to do: Add Cache-Control: max-age (for example 86400 for 24 hours). Without it, receivers guess - and some ignore the content.
• ✓
  pass: The file follows the official SI schema (current (3.4/3.5))

  Validated against the schema published by WorldDAB/RadioDNS.
