OK, I am confused and DNS is the reason.
So, Comcast, 13 public IP's bound to my modem.
Each public IP has a DNS name from comcast (they assign it automatically) like:
173.13.167.209 --> 173-13-167-209-sfba.hfc.comcastbusiness.net
I created a DNS entry at GoDaddy for 173.13.167.209 that is 'inhouse.theindiecompanyllc.com'
When eth0 is alive, I see that it tells me my name is 173-13-167-209-sfba.hfc.comcastbusiness.net since I am using a comcast DNS Server.
So if I setup my own internal caching name server for 173.13.167.209 then I have a third name or can I just use the GoDaddy DNS entry I gave it? Do I then set my systems to use my local name server for their information and not Comcast? How does that effect internet browsing where I dont have entries for google.com, etc in my local name server?
Lastly, If I have two NICS (one is 173.13.167.209 and second private internal IP) For my local name server I would have two entries, one for public and one for the private card so I can do something like 'inhouse.local' and get intranet or ssh inhouse.local, etc correct?
I see that Paul Heinlin put out a DNS tutorial here: http://www.madboa.com/geek/soho-bind/ Paul, I appreciate this!
