I just installed a system using FreeBSD-11.1-PRERELEASE-amd64-20170519-r318507-memstick.img. I had the wrong NIC plugged in without realizing it, so I failed to acquire a DHCP lease twice before looking. After install, I'm noticing that /etc/rc.conf has one ifconfig_re0="DHCP" line per attempt, so three in total: ifconfig_re0="DHCP" ifconfig_re0="DHCP" ifconfig_re0="DHCP"
FreeBSD is better off this way. Sorry for the bother.
