The only thing that a ping and DNS requests have in common is that they
use IP (ICMP and UDP respectively). This indicates a broken network,
most probably a NIC card that has joined you at home and snuck into you
bed! ;) In Australian slang, it has gone "walkabout".
You might try 'bouncing' the interface via-
# ifconfig ed0 down
# ifconfig ed0 up
^^^
Substitute your interface here!
to see if that will wake the card.

Another indicator of flaky hardware, almost certainly the NIC. I
suggest you find a replacement...
