How to Change DNS Server Settings on Microsoft Windows?
The DNS settings on a computer running the Microsoft Windows operating system (OS) are configured in the TCP/IP properties window for the computer. The following example to change DNS server settings is based on the steps required to change the settings on Microsoft Windows 7 OS. They may differ slightly based on the specific version of Windows installed on the computer.

Step 1 – Select the “Start” menu button and click the “Control Panel” icon.

Step 2 – Select the “Network and Internet,” “Network and Sharing Center,” and “Change Adapter” menu options.

Step 3 – Choose the network connection to configure to use the public DNS server. For an Ethernet connection you would right click the “Local Area Connection” menu button and then choose the “Properties” menu option. For a wireless connection, right click the “Wireless Network Connection” and choose the “Properties menu choice. Then, enter a password if prompted or confirm that you want to modify the setting.

Step 4 – Choose the “Networking” menu tab. Then select the “Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6) menu option followed by clicking the “Properties” menu button.

Step 5 – Select the “Advanced’ menu option and then click the “DNS” menu tab. Note any DNS server IP addresses listed on this screen for future reference and clear from the window. Click the “Ok” menu button.

Step 6 – Chose the “Use the Following DNS Server Addresses” menu options. If you see any addresses listed here write them down. Then, enter the public DNS server addresses in the appropriate window. If you intend on using the Google Public DNS server your entries would be:

IPv4: 8.8.8.8 and/or 8.8.4.4.

IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844

Step 7 – Restart the network connection selected earlier for configuration. Then, repeat the steps for any additional network connections that require reconfiguration

Good list.

I would suggest that you DON"T change your ISP's default provided by your ISP's DHCP server unless you are definitely having problems. Your ISP's DNS servers may point to alternate IPs that may be used for bandwidth management purposes - by not using their alternate information, you may make network congestion worse on your connection or for others. Where you definitely want to use them is when the ISP is imposing some sort of censorship. (But, if you are already pissing off your ISP, using another DNS server may be the straw that breaks the camel's back.)

Also, various DNS servers hang on to entries for different lengths of time. If you are trying to reach a domain location that goes up & down frequently (e.g. website at the long end of a poor connection), using a DNS server that holds onto information for longer may actually make your access more stable. On the other hand, a pooled server domain is better served by DNS servers which have a short refresh.

For static connections, I would suggest #1: Google (relatively fast refresh - they can absorb the high amount of traffic); #2: Hurricane Electric (relatively fast refresh - top level DNS provider); and #3: OpenDNS (long refresh). Level3 (which includes some of the original top level DNS servers @ 4.2.2.n) has stated that it prefers the public to not access their DNS servers - they should only be referenced by downstream ISPs (who then use their DNS servers to serve end users).

How well your router / workstation manages flushing tables / refreshing entries / handling timeouts when dealing with DNS is another crapshoot once again unfortunately.
