Google Public DNS
Archived from the original on 24 March Google has their Public DNS service available on a global anycast network which provides all of the benefits of anycast for the queries made to them. Funny I thought the same. You seem to be the kind who believes in outsourcing everything, even if for short-term profit, not realizing the risks. This second level cache reduces the fragmentation and cache miss rate that can result from increasing the number of servers. Some devices use separate fields for all eight parts of IPv6 addresses and cannot accept the::

Why should you try Google Public DNS?

How to Change Your Default DNS to Google DNS for Fast Internet Speeds

In addition to monitoring their servers for bad actors, Google Public Resolvers fully support DNSSEC which allows them to guarantee the responses they are offering are authentic and from authoritative sources. One of the biggest reasons we suggest customers switch to Google's resolvers is that their network is set to use improperly configured resolvers.

It puts priority on returning the right answer to a query. In cases when there is a query for a non-existent or mistyped domain name, users get an NXDOMAIN response, which indicates no known response, to their query. Now that we've investigated why you might want to use Google's Public DNS let's take a look at what you need to do to use it. Configuring your settings will vary based on the operating system and device you are using. You will also likely need administrative control of your computer to change these settings, but you should be able to adjust the DNS settings for your system whereever you would adjust other network settings.

Your second point is simply not true John. If your network adapter is still pointed at the DNS say…. Which is why DNS servers exist in the first place!

John Wood, better late than never. Your point is correct. Google does not have just one set of servers at those IPv4 addresses but many. That was with just IPv4. IPv6 brings on a whole new set of complications.

I will need to also handle IPv6 fairly soon. Now, lets lower the boom. More on that in a moment. Is the beast dead or not? If it is dead not in DNS say it is dead and more on. But you want it to really show that it is dead in a script and how is the DNS server to know that you are interactive or using a DNS checking script?

I have two main activiites. One is review Phish at PhishTank for whether they are still a phish or not. I also help at MalwareDomainList and for myself in block lists of malware hosts. The last thing I need is a DNS service or something else between me and what ever saying this host has phish or malwre.

Let me just say this is a lot more complicated than you think it is. DNS servers can be a controversial topic. They cannot get accurate enough time and as I write this are busily replacing Cesium clocks with even better ones. I want the best DNS results I can get. I frown on that.

Why using Google DNS / OpenDNS is a bad idea
