Just after reboot, I couldn't ping my default router and my DNS server or
anywhere in the world:
$ ping www.vt.edu
ping: sendto: cannot resolve www.vt.edu: Host name lookup failure
$ ping 198.82.82.1 (my default router)
ping: sendto: Host is down
$ ping 198.82.82.66 (my first nameserver in resolv.conf)
ping: sendto: No route to host
I do have defaultrouter="198.82.82.1" in my /etc/rc.conf. I can get
connectivity only after I do a "dnsquery www.vt.edu" ( it fails the first
few times also). But after some time, it loses connectivty again.
I guess it is more of a routing problem than DNS problem, but jsut couldn't
figure it out.
