  pass: Registered

  09790.4659.4a0.fm.radiodns.org points to the station's authoritative domain: radiodns.hubbardradio.com

2. Service discovery (SRV records)

• !
  warn: SRV target radiodns.hubbardradio.com 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.hubbardradio.com its own A/AAAA record (or point the SRV record at the real host name).
• ✓
