• i
  info: RadioDNS lookup name

1. RadioDNS registration

• ✓
  pass: Registered

  09210.5a55.5a0.fm.radiodns.org points to the station's authoritative domain: r1dns.com

2. Service discovery (SRV records)

• ✓
  pass: _radioepg._tcp.r1dns.com published

  priority 0, weight 100, port 80 -> r1dns.com
• !
  warn: Only the older _radioepg record is published

  What to do: Add _radiospi._tcp.r1dns.com on port 443 as well, so receivers that use HTTPS can find the SI file.

  info: _radiovis._tcp: not published

  Slideshow/visuals (STOMP) - optional, only needed for a live slideshow service.

5. Logos

• !
  warn: Not all five standard logo sizes are listed

  Missing: 32x32, 112x32

  What to do: Add Cache-Control: max-age (for example 86400 for 24 hours). Without it, receivers guess - and some ignore the content.
