I want to try OpenDNS. To that extent, in my Vonage/Motorola phone modem VT2442. I switched to type Static (from DHCP) and changed DNS 1 and DNS 2, and saved. However, I was then asked for a “Mask” (empty now). In DHCP, the mask is 255.255.224.0. Should I use the same mask in Static? In case I would be asked for a Gateway after I fill in the mask, it is 76.189.192.1 in DHCP. Should I use the same in Static?
