What is being checked
- info: WGLT - NORMAL, ILFrom the NRSC list: 89.10 MHz, PI code 65B1, FCC facility 28310.
- info: RadioDNS lookup name08910.65b1.6a0.fm.radiodns.org (frequency 89.10 MHz, PI 65B1, country code 6a0)
1. RadioDNS registration
- pass: Registered08910.65b1.6a0.fm.radiodns.org points to the station's authoritative domain: radiodns.prss.org
2. Service discovery (SRV records)
- info: _radiospi._tcp.radiodns.prss.org: not published
- pass: _radioepg._tcp.radiodns.prss.org publishedpriority 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 aliasDNS 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 publishedWhat to do: Add _radiospi._tcp.radiodns.prss.org on port 443 as well, so receivers that use HTTPS can find the SI file.
- info: _radiovis._tcp: not publishedSlideshow/visuals (STOMP) - optional, only needed for a live slideshow service.
