Is that dhcpclient, or dhclient?

What is the output of these commands?
rpm -qa | grep dhc
# to see what's actually installed as a package
find / -name dhclient
# to see if and where is the executable installed
grep -rI dhclient /etc | grep -v selinux | grep -v /ifup-eth: \
| grep -v /ifdown-eth:
# to see if it's called from somewhere else than the regular places
