Clearly you are having dns problems.
First, try a dig with the +trace flag, eg:
$ dig +trace www.freebsd.org.
; <<>> DiG 9.8.3-P1 <<>> +trace www.freebsd.org.

Note the isc-sns.com/net/info addresses. These are our public-facing
DNS servers and are distributed around the world.
You should see something like this:
$ host ns1.isc-sns.net
ns1.isc-sns.net has address 72.52.71.1
...
ns2.isc-sns.com has address 38.103.2.1
ns3.isc-sns.info has address 63.243.194.1
It would be interesting to see traceroutes to these IP addresses.
You had problems above with the nslookup commands. You might try this:
$ nslookup www.freebsd.org ns1.isc-sns.net
Server: ns1.isc-sns.net
Address: 2001:470:1a::1#53
www.freebsd.org canonical name = wfe0.ysv.freebsd.org.
Name: wfe0.ysv.freebsd.org
Address: 8.8.178.110
or even:
$ nslookup www.freebsd.org 72.52.71.1
Server: 72.52.71.1
Address: 72.52.71.1#53
www.freebsd.org canonical name = wfe0.ysv.freebsd.org.
Name: wfe0.ysv.freebsd.org
Address: 8.8.178.110
What does your /etc/resolv.conf file look like?
What happens if you change it to (as a debugging aid):
$ cat /etc/resolf.conf
nameserver 8.8.8.8
nameserver 8.8.4.4
Does that change anything?
