The output of the domainname command hasn't ever worked the way you
would expect on Redhat to my recollection. quite simply the Redhat
network scripts have never set the variable unless you configure NIS
and nothing expects it to be set any more.
'hostname -d' should give you the output you are looking for.

dnsdomainname is a symlink to the hostname command which reads the $0
to determine its behavior its effectively an alias to hostname -d but
it may or may not work on various different versions and distros.

domainname returns the NIS domain names e.g.( hostname -y)  which does
not have to match the FQDN its important to know if you are using NIS
which many people still are than this becomes important but otherwise
you should ignore it.

all of this is explained in the hostname man file 'man hostname'
