TMO Quick Tip - OpenDNS: Managing Your Internet Access
by , 9:15 AM EDT, September 5th, 2008
Most people never think about the Domain Name Servers their ISP provides, and for the most part they probably handle their part in serving up Web pages just fine. If you want more control over content the Internet feeds you, however, your service provider's DNS services may well fall short. That's where OpenDNS comes in.

First, a quick DSN primer: Domain Name Servers handle to process of converting the URLs you enter in your Web browser into the addresses that identify the Web site you are viewing. For example, if you type www.apple.com in your Web browser, a DNS server will change that to 17.149.160.49.
Here's what makes OpenDNS better: OpenDNS lets you block content you don't want on your network or computer, it includes a built-in phishing scam protection system, supports domain blocking, and fixes typos in the URLs you enter. It also includes statistics tracking so you can see what type of Internet activities are happening on your network.

To add the OpenDNS servers in Mac OSX 10.5, do this:
- Choose Apple menu > System Preferences.
- Select the Network Preference Pane.
- Select your network connection from the column on the left, and then click the Advanced button.
- Choose the DNS tab.
- Click the Plus button to add a new DNS server, and then enter 208.67.222.222
- Click the Plus button again and enter 208.67.220.220
- Click OK
- Click Apply
OpenDNS is free, and you can sign up at the OpenDNS Web site.

If you edit the DNS settings in your router, assuming your router assigns IP addresses to your various computers on your LAN, which is typically the case, then you don't have to edit the DNS in each computer per this tip.
Make sure yuo delete the ones that may appear in your router configuration table as they came from the DHCP server at your ISP and you don't want them listed before the Open DNS addresses.
Finally you don't need to enroll in Open DNS to uses thes IP addresses. They always work.
I want to know the following : I have a Mac connected through the Modem to the ISP. The Mac as well as Modem have DNS settings. Now, when i enter a website url in Safari, which of the two resolves the domain name? And, if i have set the Mac DNS to openDNS while the modem DNS to ISPs, does the ISP DNS play any role ?
