DNS: What is it and why do you need to choose a type? DNS is short for Domain Name System, a system that converts a domain name into an IP address, allowing users to easily access sites on the Internet. When you enter a website's address into your browser, your computer sends a request to the DNS server, which returns the site's IP address. This allows your computer to establish a connection to the site. However, there are different types of DNS servers, and the type you choose can affect the speed and security of your Internet connection. For example, open DNS servers such as Google Public DNS and OpenDNS may be faster, but they do not protect your privacy. On the other side of the spectrum, there are DNS servers that provide secure access to the internet, such as DNSCrypt and DNS-over- TLS. These services encrypt your DNS requests, making them impossible for third parties to view. Therefore, choosing the right DNS server can help improve the speed and security of your Internet connection. But before choosing, you need to consider any features such as availability, speed and security. DNS is a domain name system that turns domain names into IP addresses. There are several types of DNS, each with their own advantages and disadvantages.
The first type of DNS is recursive DNS. It performs DNS queries on behalf of the client and queries other DNS servers for information until it finds the correct IP address. Its advantages are that it quickly finds the desired IP address and does not require configuration by the user. The downside of recursive DNS is that it can be susceptible to attacks such as DNS cache poisoning.
The second type of DNS is authoritative DNS. It stores information about domain names and IP addresses and responds to DNS queries from other DNS servers. The advantage of an authoritative DNS is that it provides reliable and secure communication between DNS servers, but the disadvantage is that it requires configuration and maintenance.
The third type of DNS is caching DNS. It stores information about domain names and IP addresses that it has received from other DNS servers and uses them to quickly respond to DNS queries. The benefit of caching DNS is that it reduces network load and speeds up responses to DNS queries. The downside is that it may store outdated data and not update it on time.
Taking it all together, each DNS type has its own advantages and disadvantages. The type of DNS you choose depends on the specific needs of your network and your risk assessment.
How to choose DNS: basic selection criteria
The choice of DNS server can have a significant impact on the speed and stability of your network. When choosing a DNS server, you should consider the following criteria:
- Speed. The DNS server must provide fast access to the requested sites.
- Reliability. The DNS server must be stable and reliable to avoid network disruptions.
- Safety. The DNS server must have mechanisms to protect against DNS attacks and fraud.
- Geographical accessibility. The DNS server should be located close to your location to improve response time.
When choosing a DNS server, you can use either public or private servers. Public DNS servers, such as Google DNS or OpenDNS, are widely used and provide fast access to websites. However, private DNS servers operated by companies can provide greater network security and reliability. In any case, the choice of DNS server should be balanced and based on the above criteria.
DNS servers are special computers that are responsible for translating domain names into IP addresses. When you enter a site's address into your browser, your computer sends a request to the DNS server, which responds with the site's IP address. Without a DNS server, you wouldn't be able to visit any website.
How to choose the best DNS server? There are several options. You can use your ISP's DNS server or choose a public DNS server such as Google Public DNS or OpenDNS. Each provider offers its own DNS servers, which may be faster than public servers. But if you have a slow Internet connection, then it is better to choose a fast DNS server.
It is also worth paying attention to safety. Some DNS servers block sites with malicious content and protect you from phishing attacks. For example, OpenDNS has the function of blocking sites related to drugs, pornography, gambling, etc.

The choice of DNS server can affect the speed of loading sites and the security of your Internet connection. If you want to know which DNS server is better to choose, then it is best to test the loading speed of sites with different DNS servers and choose the fastest and most secure option.
DNS (Domain Name System) is a complex system responsible for resolving domain names into IP addresses. There are several types of DNS servers, and each of them performs different functions.
Resolvers are DNS servers that are responsible for translating domain names into IP addresses. They make queries to other DNS servers if they cannot find the information they need themselves. Resolvers can be either local or remote.
Replicators are DNS servers that store copies of DNS zones. They are used to provide fault tolerance and fast access to data. Replicators can be either masters or slaves, and they automatically synchronize data among themselves.
Proxy servers are DNS servers that are designed to speed up queries to other DNS servers. They cache requests and responses, allowing you to retrieve information faster. Proxy servers can also perform the functions of filtering requests and blocking unwanted sites.
Each type of DNS server has its own characteristics and advantages, and the choice of a specific type depends on the needs and conditions of use. It is important to remember that properly configuring and maintaining DNS servers is key to an efficient network.
DNS services play an important role in the operation of the Internet. They help translate domain names into IP addresses, which allows you to establish a connection to the desired server. However, not all DNS services are equally effective. Using a better DNS service can increase your internet connection speed and improve your overall network performance.
There are several DNS services that are considered the best in their category. These include Google DNS, OpenDNS and Cloudflare DNS. Google DNS is one of the most popular DNS services due to its high speed and reliability. OpenDNS, on the other hand, offers additional features such as blocking malicious sites and content filtering. Cloudflare DNS, on the other hand, is known for its DDoS protection and fast speed.
Choosing the best DNS service depends on your needs. If you are looking for a fast and reliable DNS service, Google DNS is a great choice. If you want additional security and control over your network, OpenDNS is the way to go. And if you are looking for a DNS service that can protect your network from DDoS attacks and provide high speeds, Cloudflare DNS is the way to go.
In any case, choosing the best DNS service can significantly affect your network performance and internet connection speed. Therefore, you should not neglect this important aspect of the internet. Choosing a DNS server is one of the important steps towards safe internet use. DNS servers translate domain names into IP addresses needed to establish a connection. Depending on the type of DNS server you choose, you can increase the security of your internet connection.
The most popular type of DNS server is a public DNS, provided by Google, Cloudflare, OpenDNS, and others. They provide a fast connection, but they do not always guarantee security. However, if you choose a DNS server that supports the DNS-over-HTTPS (DoH) protocol, you can protect your data from eavesdropping and phishing.
Another type of DNS server is a local DNS, which provides a higher level of security. It only works within your local network and is not susceptible to attacks from outside. Local DNS can also block malicious sites and content, which increases the security of your network.
In any case, choosing a DNS server depends on your needs and security requirements. If you want a fast connection, then public DNS is the best choice. If you want maximum security, then local DNS is what you need. But you can also choose DNS servers that support DoH to get a combination of speed and security.
