When people email us requesting cooperation with their DNS configuration, we usually point them at DNS lookup tools to diagnose problems. Still, sometimes we’re ready to narrow down issues to local or ISP provided resolvers. At that point, we occasionally recommend changing to Google’s Public DNS. Here’s how you can accomplish that and why you might want to inspect it.

Google’s Public DNS is fast.

Google has the Public DNS service possible on a global anycast network that includes all of the benefits of anycast for their questions. For substantially the same reasons that authoritative name servers on an anycast network provide a speed change to your clients, anycast resolvers perform speed assistance to you by implementing your browser to secure calls to the nearest name server available.

Additionally, Google has taken several steps to reduce latency in DNS queries, including some exciting measures for resolving cache misses across their infrastructure.

Using Google’s Public DNS provides increased security.

One of the more significant problems with publicly available resolvers is that they could be used in Denial of Service and Amplification attacks by making a small query that returns a considerable response. Google has taken several measures to protect against some of the most common attacks and monitors their resolvers carefully to ensure bad actors cannot misuse their service. In extension to monitoring their servers for bad actors, Google Public Resolvers fully support DNSSEC, enabling them to guarantee the responses they are submitting are authentic and from authoritative references.

One of the most significant reasons we recommend customers switch to Google’s resolvers is that their network is set to work improperly configured resolvers. Implementing correct results is one of the key advantages which Google Public DNS affords. It puts the priority on returning the correct answer to a query. When there is a question for a non-existent or mistyped domain name, users receive an NXDOMAIN response, which symbolises no known reaction to their question.

How to handle Google Public DNS

Now that we’ve reviewed why you might require using Google’s Public DNS, let’s view what you need to do. Configuring your settings will alter based on the operating system and device you are using. You will also possible necessary administrative control of your computer to update these settings. Still, you should accommodate the DNS settings for your system wherever you would change other network settings. You should utilise the following addresses, or even just the IPv4 addresses, as your DNS servers.

Google’s Public DNS IP addresses (IPv4) are:

8.8.8.8

8.8.4.4

Google’s Public DNS IPv6 addresses are:

2001:4860:4860::8888

2001:4860:4860::8844

Hopefully, this lead will help you circumvent DNS configuration problems and give you a more reliable resolution.
