There are lots of reasons you might want to try alternative ones (we get into many of them in Why Use Different DNS Servers? Find out if your ISP is having DNS problems Your ISP could be the source of the problem. When a request is made for a DNS record, the browser cache is the first location checked for the requested record.In chrome, you can see the status of your DNS cache by going to chrome://net-internals/#dns.The operating system level DNS resolver is the second and last local stop before a DNS query leaves your machine.
About This Site. If it does not, it then sends a DNS query (with a recursive flag set), outside the local network to a DNS recursive resolver inside the Internet service provider (ISP).When the recursive resolver inside the ISP receives a DNS query, like all previous steps, it will also check to see if the requested host-to-IP-address translation is already stored inside its local persistence layer.The recursive resolver also has additional functionality depending on the types of records it has in its cache:To provide you with the best possible experience on our website, we may use cookies, as described Someone from Cloudflare will be in touch with you shortly. De Domain Name Server (DNS) is een server welke webadressen vertaalt, zodat je browser er mee om kan gaan. If there are any IP addresses listed in the Preferred DNS server or Alternate DNS server, write them down for future reference. To learn how this process works, it helps to follow the path of a DNS lookup as it travels from a web browser, through the DNS lookup process, and back again. By using a combination of these queries, an optimized process for DNS resolution can result in a reduction of distance traveled.

Dit kan helpen bij het constateren of de DNS server van de ISP misschien de fout veroorzaakt.
This is the server at the bottom of the DNS lookup chain that will respond with the queried resource record, ultimately allowing the web browser making the request to reach the IP address needed to access a website or other web resources.An authoritative nameserver can satisfy queries from its own data without needing to query another source, as it is the final source of truth for certain DNS records.It’s worth mentioning that in instances where the query is for a subdomain such as foo.example.com or There is a key difference between many DNS services and the one that Cloudflare provides.Different DNS recursive resolvers such as Google DNS, OpenDNS, and providers like Comcast all maintain data center installations of DNS recursive resolvers. When a user wants to load a webpage, a translation must occur between what a user types into their web browser (example.com) and the machine-friendly address necessary to locate the example.com webpage.In order to understand the process behind the DNS resolution, it’s important to learn about the different hardware components a DNS query must pass between.
In an ideal situation cached record data will be available, allowing a DNS name server to return a non-recursive query.The purpose of caching is to temporarily stored data in a location that results in improvements in performance and reliability for data requests. These resolvers allow for quick and easy queries through optimized clusters of DNS-optimized computer systems, but they are fundamentally different than the nameservers hosted by Cloudflare.Cloudflare maintains infrastructure-level nameservers that are integral to the functioning of the Internet. DNS translates domain names to Each device connected to the Internet has a unique IP address which other machines use to find the device.

One way to think about the difference is the The recursive resolver is the computer that responds to a recursive request from a client and takes the time to track down the Put simply, an authoritative DNS server is a server that actually holds, and is responsible for, DNS resource records. The example below outlines all 8 steps when nothing is cached.Once the 8 steps of the DNS lookup have returned the IP address for example.com, the browser is able to make the request for the web page:The DNS resolver is the first stop in the DNS lookup, and it is responsible for dealing with the client that made the initial request. By using a combination of these queries, an optimized process for DNS resolution can result in a reduction of distance traveled.
