DNS service & D-Link DVG-1120M

My settings and question are at the bottom of this. I use AttCallvantage over Comcast Broadband.

I've received the following letter:

The details depend on the device you are using as router, and the protocol used by the ISP to supply IP address and other parameters (default gateway, netmask, and, indeed, DNS servers addresses). I'm not familiar with either the D-Link DVG-1120M or Comcast, but I guess the latter uses DHCP, and most likely the DVG-1120M is already configured for using DHCP to get the other parameters: so, probably all you have to do is, as you say, leave the DNS fields blank not to override the address values obtained with DHCP.

Funny thing is that the D-Link will not accept "blank", only 0.0.0.0.

But yes, ATA and router and PC all use DHCP (daisy changed) but it is that ATA that is the connection to comcast.

It worked! 0.0.0.0=>ATA save and reboot; pwr cycle router; release/renew on PC and voila, new DNS addresses!

In NE I'm seeing dns1: 68.87.71.226 - 10 hops (was 17!) dns2: 68.87.73.242 - 19 hops (was 13 when using 4.2.2.4/3)
