Partial answer due to the late hour here.
You probably have NetworkManager-config-connectivity-fedora installed which will
connect with http://fedoraproject.org/
on a periodic basis.
188.8.131.52 is an IP address associated with fedoraproject.org
[root@meimei conf.d]# host 184.108.40.206
220.127.116.11.in-addr.arpa domain name pointer proxy10.fedoraproject.org

, however the only problem is I should NEVER see
an arp entry for an IP address not on my subnet
and obviously 184.108.40.206 is not on my subnet of 172.18.19.0/24.
so the original question remains, why am I seeing an ARP entry for an IP
address not on my subnet.
second, somewhat new question, how do I stop networkmanager from polling
