It may be worth having a read of this thread before you decide on OpenDNS. There are other DNS services available that arguably now offer better security and possibly better speed too (depending on your location).

Someone will correct me if this has changed recently, but if (like me) your ISP issues you with a different IP address every time you connect, then OpenDNS will not save any preferences you may have set unless you update these too manually. I did try a third party auto updater for OpenDNS a while ago, but mostly it either wouldn't load with Windows or failed to work anyway.

As Sope says there are plenty of other alternatives now. I use Comodo Secure DNS and have been very happy with their service.

This is true, but I think if you only use OpenDNS for basic DNS purposes your IP address doesn't matter. If you create an account to use the advanced feature then it does.

I stopped using OpenDNS when they removed some of their security features for the free account users.
I now use DNS Advantage.

I have two computers, a desktop and a laptop. The desktop is connected to the internet by an ADSL router to BSNL as the service provider. I noticed that I was quite often seeing a "looking up" message in the status bar of my browser. I then switched my DNS from the BSNL ones to Google (8.8.8.8 and 4.4.4.4) and have had no such problem since.

My laptop uses a 1XCDMA USB internet service from Reliance Communications. With this, apart from the generally poor service (since I'm not located in a metro where I would get really good speeds), I haven't found a way to change the DNS. So I'm stuck with what the ISP has provided.

Thanks for the heads up Sope :) - I'm switching from OpenDNS to DNS Advantage to give it a try. :D

Glad my post helped.

I felt a bit let down when I found out OpenDNS had apparently changed the level of security they offer for free account users. From what I can gather, they still block phishing sites and botnets but not malware sites (for this it appears you now need their extremely expensive Enterprize account!)

In contrast DNS Advantage claims to block all these types of sites amongst other potential security risks. It looks like Comodo Secure DNS also offers the same service as it appears to use the same system of servers i.e. Neustar UltraDNS. Either of these now seem to be a better choice over OpenDNS in my view.

I've been using DNS Advantage for well over 6 months now and have never had a problem with it :)

If anyones interested here's a couple of tools to test/compare various DNS speeds :-

http://code.google.com/p/namebench/
I found these interesting to play with when choosing a DNS though of course I still based my decision on the level of security offered rather than all out speed.

Thanks for the valuable information Sope. I'd no idea OpenDNS had downgraded its free security service. I've now switched to DNS Advantage and it seems to work just fine - speed certainly no issue.

Cheers! :)

Have also just switched from Open DNS to DNS Advantage, mainly because the free version in Open DNS appears to have less security. :(

I have an account with Open DNS but have no idea how to cancel it! :rolleyes:

I used DNS Bench over a couple of days and at different times and speed wise there was very little in it; will be sticking with Advantage until I am informed that there is something quicker and more secure out there. :)

I've been using Comodo DNS for the last few hours. No +/- in performance here in Bombay, India compared to Google DNS.

By the way, how can one test the "security" aspect? Type a "nasty" URL in and see if it is rejected? What exactly happens? Does someone have a nasty site to suggest (if forum rules permit)?
