Open DNS


[link to this post]
 
What views does anyone have on Open DNS?

I've seen references to it before, and have just read this recommendation.

It works... but if your ISP runs a properly set-up DNS service there's little point in swapping.

If doesn't (and many don't!) then it may well be worth using.


That's for the free "home" version, if you use (and pay for) the business version then the extra control and security options may well make it worthwhile.

I've been using it for over 3 years. It has been most effective in controlling junior's surfing habits. I'm sure it will continue to work until he realises he can put his own dns server addresses in to his laptops connection parameters.

I'm mainly curious.

In the Network Pane of my PB, under the TCP/IP tab for Airport, there are two DNS Servers listed, and in parentheses alongside it says (Optional).

I vaguely remember entering them some time ago, probably on the advice of someone at Zen.

Block outgoing port 53 in your routers firewall if you want to prevent this.

Normally you'd just put the router's LAN address in there and rely on it picking up your ISP's DNS servers when you log in.

I tried the OpenDNS servers against my ISP's own (putting them in the router, not the computer)... the primary was slightly quicker than OpenDNS, the secondary was slightly slower.

And I mean slightly, sub-millisecond, which could easily have been due to traffic variations.

So I just let the router pick them up from my ISP.

I think that's what the Intel iMac does (10.6.8)

We've got an AEBS. In its TCP/IP tab it shows 10.0.x.x by default.

That's the operative point! Many ISP's DNSs fail from time to time.

Best defence is to mix-and-match 1 ISP DNS with 1 public DNS.

I've been using OpenDNS for a long time now ... I think I changed because there were problems with O2's own DNS servers at one point. Don't know if this is still the case. I actually have OpenDNS and Google public DNS configured with O2's primary 5th as my router doesn't allow me to delete this.

Never had any DNS problems but then I have 3 different providers with 5 servers configured.
