Well remote side (the beagleclone running linux) is hardwired to 
169.254.99.130 and somehow the Ubuntu box I plug it into sorts that out.

On MAC same thing happens:
en5: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
     ether 5e:7e:b7:b1:2b:ba
     inet6 fe80::5c7e:b7ff:feb1:2bba%en5 prefixlen 64 scopeid 0xe
     inet 169.254.99.129 netmask 0xfffffffc broadcast 169.254.99.131
     nd6 options=1<PERFORMNUD>
     media: autoselect (10baseT/UTP <full-duplex>)
     status: active


I can look at avahi-autoipd though.  See what comes from it.

Thank you Ed.
