As a system engineer, you have been tasked with testing and

configuring a Domain Name System $($DNS$)$ server on the

Internet Protocol $($IP$)$ address $192\mathrm{.}168\mathrm{.}2\mathrm{.}10.$ You must verify

the server is up and running, as well as create new resource

records to ensure the server is configured correctly.

Notes: $$

Domain:

net.plus.com

Shorthand Domain:

plus.com

Mail Server:

mail.net.plus.com

IPv$6$ Address: $2001$:db$8$:$85$a$3$::$8$a$2$e:$370$:$7334$

Verify $($by scanning both TCP and UDP ports$)$ that the DNS port is open and accessible on the host remotely, from a separate

machine, using this command:

Results: $22/$tcp open, $21/$tcp open, $123/$udp open, $139/$tcp open, $445/$tcp open

Is the port for DNS open and accessible?

Yes

No

To check internally, which command should be used locally

on the DNS server itself to see if the port is listening?

After reconfiguring your network, you need to set up DNS resource records to ensure connectivity from the outside.
