There are two main benefits of using a secondary DNS server: Redundancy and resiliency: Relying on just one DNS server creates a single point of failure. If the primary server fails or is compromised by an attack, prospective visitors can no longer access the desired domain.
Is it normal to have two DNS servers?
At a minimum, you’ll need two DNS servers for each Internet domain you have. You can have more than two for a domain but usually three is tops unless you have multiple server farms where you would want to distribute the DNS lookup load. It’s a good idea to have at least one of your DNS servers at a separate location.
Why are there 2 DNS servers listed in the output?
Provides redundancy in case the primary DNS server goes down. If there is no secondary server, when the primary fails, the website will become unavailable at its human-readable domain name (although it will still be accessible by its IP).
Why would a computer have multiple DNS servers?
Primary and Secondary DNS Servers In most cases, a primary and a secondary DNS server are configured on your router or computer when you connect to your internet service provider. There are two DNS servers in case one of them happens to fail, in which case the second is used to resolve hostnames you enter.
What is the purpose of a secondary DNS server?
By adding a second DNS provider, you have two separate DNS networks running simultaneously. These two networks provide backup for each other and for your users in the event one network is offline or has degraded performance.

What is the default DNS server?
Every time a new domain name is registered, it is assigned to a set of name servers, also known as default name servers. These name servers are the default name servers for the particular registrar or hosting company and are used to keep the domain name live from the beginning.
How do I find my primary DNS on my router?
The easiest way to find out your dns server IP address is to go through the router’s admin interface status page. All routers have a built-in web-based setup page that allows the user to customize settings and set view properties such as IP address and dns settings.
What is the difference between a primary server and a secondary server?
A primary server is a server that acts as the first source for Domain Name System (DNS) data and responds to queries. It can be contrasted to the secondary server, which acts like the primary server but does not have the same access to data.
Is 1.1.1.1 still the fastest DNS?
The independent DNS monitor DNSPerf ranks 1.1.1.1 the fastest DNS service in the world. Since nearly everything you do on the Internet starts with a DNS request, choosing the fastest DNS directory across all your devices will accelerate almost everything you do online.
What is a DNS server for WIFI?
The Domain Name System (DNS) Server is a server that is specifically used for matching website hostnames (like example.com)to their corresponding Internet Protocol or IP addresses. The DNS server contains a database of public IP addresses and their corresponding domain names.
What is Google’s DNS server address?
How do I use two DNS servers?
You can’t make two DNS servers reachable over a single IP since they both would use the same port (which is not configurable for the global DNS). But even if you could most registrars won’t accept two times the same ip (and some even don’t like two times the same network).
Can you mix DNS servers?
You can have different nameservers for different levels / subdomains if you are so inclined, for example (example.com at godaddy, subdomain1.example.com network solutions, subdomain2.example.com dns made easy). This is called zone delegation.
How many DNS servers are there?
Root name server overview In total, there are 13 main DNS root servers, each of which is named with the letters ‘A’ to ‘M’. They all have a IPv4 address and most have an IPv6 address. Managing the root server is ICANN’s responsibility (Internet Corporation for Assigned Names and Numbers).
How many name servers can a domain have?
How many nameservers can a domain have? At a minimum, you need only two DNS servers for each of your domains. You can also extend this to more than two for your domain, but usually, three is maximum unless you have multiple server farms where you would want to share the DNS lookup load.

There are two DNS servers in case one of them happens to fail, in which case the second is used to resolve hostnames you enter.
How do you check what DNS server you are using?
Open your Command Prompt from the Start menu (or type “Cmd” into the search in your Windows task bar). Next, type ipconfig/all into your command prompt and press Enter. Look for the field labeled “DNS Servers.” The first address is the primary DNS server, and the next address is the secondary DNS server.
Is Primary DNS the same as IP address?
Primary DNS is the main authoritative DNS server (or nameserver) that serves as the initial stop for a query as the user-entered domain name is translated into an IP address that the system can understand—after all, we don’t speak the same language, so we need a translator to help us with every website visit.
