If you are a perfectionist and want to test a large number of DNS servers, then two software programs can potentially help:ĭNS Benchmark, which works with Windows (including Windows 10) can be downloaded from the following site:Īfter several minutes of processing, the DNS Benchmark program provides an ordered list of DNS servers. Method 3: Identify the best DNS servers using DNS Benchmark or Namebench images) from numerous domains, DNS look-ups can become a “significant bottleneck” in the browsing experience. You can view the DNS server settings for the most popular ISPs by clicking on the following link:Īccording to Google, with the increasing complexity of web pages that reference resources (e.g. There may be nothing wrong with your ISP DNS servers in terms of performance it just may be that they are located much further away than a Public DNS server. Furthermore, if your ISP’s DNS servers are located a considerable distance away from you, there may be significant DNS look-up delays. If your ISP’s DNS servers are unreliable or slow (for example at peak times), your web browsing experience may be significantly affected. This means that your browsing experience is determined in part by the performance, reliability and location of your ISP’s DNS servers. In general, most routers supplied by ISPs are set up to use the DNS servers operated by the ISP. In addition, a number of third parties (such as Google, Cloudflare and OpenDNS) provide independent, so-called “Public” DNS servers. Many ISPs run their own DNS servers to provide domain name to IP address translation for their broadband users. Also, broadband users located a significant distance from the server would suffer from large time delays. It would be impractical to have a single DNS server providing the translation of domain names to IP addresses for all Internet users in the world since a single server would soon get congested by all the DNS look-ups being undertaken. This process inevitably causes a delay in the web page being rendered although, through optimisation, this delay can be minimised.Ī distributed database architecture is used with the Domain Name System, with many DNS servers located across the world to allow domain names to be translated to IP addresses for all devices is existence, despite many changes in IP addresses being made every single day. When you enter a domain name into your browser or you click a particular link, it is necessary to first translate the name into a numerical IP address so that the contents of the website can be retrieved. For example, Facebook could decide to change the server providing its web pages (and, therefore, its IP address) without needing to change the domain name. Not only is a domain name easier for people to remember, but a domain name provides flexibility in terms of how websites are accessed on the Internet.
A domain name (for example, is essentially a human-friendly version of an IP address. While the IP addressing system is a very useful identification mechanism for computer devices, it is not a particularly human-friendly means of identification. All web servers are assigned an IP address, which is a numerical label that is used to identify them and which enables them to be found on the Internet. The Domain Name System is the mechanism by which meaningful website domain names (such as or ) are translated into the IP addresses (for example, 212.58.244.26 and 74.125.129.94) of the servers providing these websites.
