DNS servers have the main function of converting domain names to IP addresses and vice versa, which makes it much easier for us to access a site like TechnoWikis.com and not enter the IP address of the mentioned site.
When we access a website, the team will contact the DNS servers that have been listed in the system and then the server searches for the IP address for that specific domain name and with it the scan request will be sent to that address IP in particular and in this way we will access the website..
Most DNS servers are provided by ISPs (Internet Service Providers) and the problem is that many of these servers do not have enough high or adequate hardware resources to support multiple requests simultaneously which triggers the access the DNS is slow or of erroneous results affecting the natural operability of the sites.
To solve this, the goal is to establish another DNS IP address in the system and the best resource is to use public DNS servers such as Google DNS or OpenDNS..
What is Google DNS?
It is developed by the giant Google and has high performance equipment which guarantees security and speed for the entire process of the necessary DNS requests.
It is important to keep in mind that Google DNS only gives us the opportunity to resolve DNS and not to use these servers to host a domain or block websites, which is a private task. The IP addresses that are implemented on these servers are:
8.8.8.8 8.8.4.4
What is OpenDNS?
The goal of OpenDNS is to provide DNS resolution services, just like Google's public DNS, only that certain additional functions are added. Among its novelties we have:
- Phishing and botnet protection
- Detailed statistics and correction of typographical errors.
When using OpenDNS there are three alternatives that are:
The IP addresses used by OpenDNS are:
208.67.222.222 208.67.220.220
We can use some of these solutions, understanding that OpenDNS has better options, but it will be necessary to pay an annual fee for acquiring greater functionality, while the free options of both will always be an ideal solution for stable navigation.
