Does Google block DNS?
Google Public DNS is purely a DNS resolution and caching server; it does not perform any blocking or filtering of any kind, except that it may not resolve certain domains in extraordinary cases if we believe this is necessary to protect Google’s users from security threats.
Which is better Cloudflare or Google DNS?
Speed and Performance In terms of speed, Google Public DNS outperforms Cloudflare. This is because of several things, including global coverage, more servers, and a shared cache. Most of the time, DNS lookups create a bottleneck, slowing down your browsing.
Should I use my ISP DNS or Google?
In addition to privacy concerns, DNS services provided by ISPs can be slower than Google or Cloudflare. This isn’t always the case, as your ISP will generally be closer to you than a third party, but many people get faster speeds with a third-party DNS server.
How do I resolve a problem with Google DNS?
Problems resolving a domain If Google Public DNS has problems resolving a certain domain name, enter it on the dns.google detail page. If the problem is with a particular DNS resource record (RR) type, enter it in the “RR type” text field (you can also enter a number). Press Enter or click Resolve to see the results.
Why is Google Public DNS returning the wrong answers?
There are many reasons Google Public DNS can return wrong answers; try any of the following that seem possible given your knowledge of the domain. Especially if the domain has new DNS servers or a new DNS registrar, Google Public DNS may be returning old (but unexpired) cached answers.
How does GeoDNS know where the user is?
Our GeoDNS has multi geological options for targeting. You can select a whole continent, countries, or regions in the US or Canada. For high accuracy, we use eDNS-client-subnet. The IPs have an extra suffix showing the location of the user. That way, we know where the visitor is coming, not just the DNS resolver he or she is using.
How can I tell if a DNS query is reaching Google?
your UDP queries are reaching Google Public DNS; if the second command’s output includes locations.publicdns.goog. your TCP queries are reaching Google too. If the output shows NXDOMAIN then you are reaching another DNS resolver.
