You removed the most important part of my comment. Which was....
PORT STATE SERVICE VERSION
53/udp closed domain
53/tcp closed domain
This mean you don't have a DNS server (bind, I assume) listening on the standard port 53
on the 108.220.213.121 interface. That means that no system outside of your internals (10.0.0.x)
can query your DNS server.
If I "telnet" to port 53 (tcp) to my ISP's name server...
[egreshko@meimei ~]$ telnet 168.95.1.1 53
Trying 168.95.1.1...
Connected to 168.95.1.1.
Escape character is '^]'.
^]
telnet> close
Connection closed.
Yours?
telnet 108.220.213.121 53
Trying 108.220.213.121...
Connected to 108.220.213.121.
Escape character is '^]'.
Connection closed by foreign host.
