Yes excuse me i was in a little haste when writing the initial mail
and quoted the wrong RFC.
This host looks like it is a part of a CDN pool of servers/hosts plus
the "offending"
part of the name appears in the far left of it indicating its host.
In essence a name describing a specific host in the aforementioned
pool. (hence a host not domain name)
"dradio_mp3_dlf_m.akacast.akamaistream.net".
If that is not enough of a reasoning you can read the associated RFCs yourself
(the correct ones this time) being 1035 (section 2.3.1) and 1123 (section 2.1)

Finally +1 for Ingo's comment this needs further investigation before
becoming a default
(i still prefer easy GUI access to enable/disable it rather than
having it default though as Julian suggested in a later reply)
