What Do I change the DNS to and do I have to change the TCP/UDP ports?

[ihaveaquestion64]

C:\Users\aidan\PegaSwitch-master>ruby rdns.rb $192.168.56.1
I, [2017-03-14T16:09:08.644173 #12936] INFO -- : Starting RubyDNS server (v1.0.3)...
I, [2017-03-14T16:09:08.644173 #12936] INFO -- : <> Listening on udp:0.0.0.0:53
I, [2017-03-14T16:09:08.659645 #12936] INFO -- : <> Listening on tcp:0.0.0.0:53

With this, what settings would I change on my switch?

Change the 'DNS Servers' on your switch to the IP of your computer.

Ok, but when the DNS server is less than fifteen characters, the switch adds more 0s to make up for that, is that ok?

[SomeoneWeird]

Yes :)

[ihaveaquestion64]

Ok, thx, I will try. Also, when I typed the command you gave for serve.py, it didn't work so I just typed serve.py to run it, would that work?

[SomeoneWeird]

You need to type python serve.py

[ihaveaquestion64]

I get this error when I type that.

C:\Users\aidan\PegaSwitch-master>python serve.py
