'cat concatenates files and prints them on the standard output' is what 
you get from the man pages for the cat command.  It's a handy way of 
looking at file contents because you can say 'cat <filename>' in a 
console and it does what you saw it do, prints the contents of the file 
to screen (which is your standard output).

When in a console you can look at the cat man pages by typing in

man cat

I'm not sure how this 'get automatically from ISP' works with respect to 
an internal LAN and the issues you've been experiencing.  All I am sure 
of with this is that the /etc/resolv.conf files have to be the same in a 
network and if you don't run DHCP on your LAN, how does the DNS 
information propagate from the router inwards?  Does the router offer a 
DNS service to the LAN?

Glad you got it working btw.
