What Are DNS Servers?

dns server

DNS servers translate the friendly domain name you enter into a browser into the public IP address that's needed for your device to actually communicate with that site.

Your ISP automatically assigns DNS servers when your smartphone or router connects to the internet, but you don't have to use those. For a lot of reasons, you might want to try alternative ones but privacy and speed are two big wins you could see from switching.

Note: Primary DNS servers are sometimes called preferred DNS servers and secondary DNS servers sometimes alternate DNS servers. Primary and secondary DNS servers can be "mixed and matched" from different providers to protect you if the primary provider has problems.

Frequently Asked Questions
Q What does a DNS server do?
The DNS server contains a list of public IP addresses associated with hostnames. It translates web addresses such as abc.com into IP addresses that are in a numerical format. In addition, DNS apps can also filter adult content, phishing sites, advertisements, and malware.
Q What are the main types of DNS servers?
The main types of DNS servers include primary and secondary servers. The primary DNS server is the preferred server, while the secondary DNS server is the alternate server. The two servers provide an extra layer of redundancy and maximize uptime.
Q How does DNS work?
DNS works similarly to a phonebook in mapping numbers and names. The servers translate website names that users type into their browsers such as nytimes.com into internet addresses. The requests made by browsers to DNS systems are known as queries.
Q Why use the public DNS Server?
Public DNS systems such as OpenDNS, Cloudflare, or Google DNS are better than the servers maintained by internet service providers. You should use public DNS servers as they offer maximum uptime, faster speeds, and increased security.
Q What to consider when switching your DNS?
Key considerations when switching your DNS provider include reliability, security, availability, and price. You should also consider the global traffic management of the company. DNS providers with global network services benefit from optimized load balancing for maximum uptime.
Q How can I find my DNS server?
To find your computer DNS server in Windows, hit the Win+R key and type CMD. Next, type ipconfig/all and look for the field address next to DNS Servers. For macOS, open System Preference from the Dock and click on Show All, and then Network. Next, click on the Advanced tab and then DNS.
You can also view your DNS server on your smartphone. Tap on the Wi-Fi icon and then click on the available network. You can see the network details of the selected network, including the DNS address.
Q What does flushing a DNS do?
Flushing a DNS will clear your computer’s DNS and IP address record. This can help resolve internet connection and security issues.
Q Why use different DNS Servers?
Using different DNS servers is recommended as it will result in a faster internet connection. In addition, it will protect your website against DNS-based attacks such as DNS hijacking, cache poisoning, DDoS attacks, and DNS tunneling.
