BK/Dan et al:
  No, because there is a filter at UCSD which requires
you to be registered
 in the 
AMPR.ORG DNS.  You are not.  Once that is in place you should be able
 to traceroute and ping your 44.44.107.1 address from anywhere on the great
 unwashed Internet.  I would register you but I don't know your callsign. 
From his allocated block notes authored by me 6 months ago:
Dan;
You'll need to email me your DNS requests manually
  In the meantime, if you set up a tunnel to another
44-net address, you should
 be able to ping it even though you're not in the DNS as the filter only affects
 non-44 inbound Internet traffic.  I often test tunnels by seeing if I can
 ping to 
n1uro.ampr.org, 44.88.0.9, which is dependably there. 
n1uro@gw:~$ ip ro get 44.44.107.1
44.44.107.1 via 23.30.150.141 dev tunl0  src 44.88.0.1
    cache  expires 574sec mtu 1480 window 840
n1uro@n1uro:~$ ping.pl 44.44.107.0/24

so far no answer... whereas
