Kind of, see man hostname
"If a machine has multiple network interfaces/addresses or is used in
a mobile environment,  then  it  may  either  have  multiple
FQDNs/domain  names  or  none at all. Therefore avoid using hostname
--fqdn, hostname --domain and dnsdomainname.  hostname --ip-address is
subject to the same limitations so it should be avoided as well."

Not a big deal, but in that case, I'd say
hostname -A does it as well.
