The specification says the iodef field contains a URL so normal URL
resolution applies.
https://tools.ietf.org/html/rfc8659#section-4.4
Questions about CNAMEs are at the wrong layer. HTTP URLs can refer to
CNAMEs; email addresses only use CNAMEs if you like tackling
interoperability problems dating from the 1980s.
