Replying to myself, it seems that when the DHCP lease is renewed,
the ARP table becomes stale in some fashion:

[apple] /usr/home/ianf $ arp -an
? ( at 00:0e:0c:6b:25:5e on ath0 [ethernet]
? ( at 00:0f:3d:a9:98:c4 on ath0 [ethernet]
? ( at 00:16:17:7d:c5:b0 on ath0 [ethernet]
? ( at ff:ff:ff:ff:ff:ff on ath0 permanent [ethernet] is my gateway.

After a lease renewal the arp table looks exactly the same as above,
yet I am unable to reach  If I manually delete the arp
entry, then I can once again reach that host.
