NIS2011 and Router Firewall

NIS 2011 v 18.6.0.29

Vista Home Premium 32 bit

 

OK I have a router that my desktop is plugged into.

 

Under my local area connections details, I see the following

 

IPv4 Address  (shows my router IP address)

 

IPv4 Default Gateway shows a 192.xxx.xxx.xxx  number

 

IPv4DHCP Server  shows same 192.xxx.xxx.xxx address as above

 

But then under

IPv4 DNS Servers  XXX.XXX.XXX.XXX

it shows two of these entries and the IP address is from my Internet Service provider. The two IP address are the same, except for the last digit

 

I thought that using a router, all these entries would be of the 192.xxx.xxx.xxx variety?

 

Is my router not hiding my IP address??
