Can you have multiple primary DNS servers?
You can have as many Primary DNS zones as you wish in your environment.
again, one server can host multiple zones.
Or if you wish you can have multiple DNS servers each hosting a primary zone.
Why do I have 2 DNS servers?
The DNS requires that all zones be redundantly supported by more than one name server. Designated secondary servers can acquire zones and check for updates from the primary server using the zone transfer protocol of the DNS. The backup DNS servers (one or more) will be slaves to your primary DNS server.
Can multiple DNS servers be configured using Active Directory?
To make the deployment of multiple DNS servers easier you should use Active Directory integrated zones. You can only use AD integrated zones if you have DNS configured on your domain controllers. Security: If you enable secure dynamic updates, then only authorized clients can update their records in DNS zones.
Do I need a secondary DNS server?
A DNS server can be primary for one zone (domain) and secondary for another. The DNS specifications (RFCs) require that each domain name is served by at least 2 DNS server for redundancy. Only one DNS server should be configured as primary for a zone, but you can have any number of secondary servers for redundancy.
Do I need 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.
What is default gateway IP?
Ad. In the networking world, a default gateway is an IP address that traffic gets sent to when it’s bound for a destination outside the current network. On most home and small business networks—where you have a single router and several connected devices—the router’s private IP address is the default gateway.
How many name servers should be visited?
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.
What is the primary DNS of my router?
Look at the IP Address field to identify your IP address; the first number in the DNS Servers field is your primary DNS; and the Default Gateway field lists the current default router address used to connect your computer to the Internet.
Should DNS be on domain controller?
In a small environment, at least one domain controller (DC) should be a DNS server. It is possible to install DNS on servers which are not DCs, including non-Windows servers, but installing DNS on DCs allows the use of AD-integrated lookup zones (see below), which improve security and simplify zone replication.
What happens if you don’t configure DNS forwarding?
Without forwarding, all DNS servers will query external DNS resolvers if they don’t have the required addresses cached. This can result in excessive network traffic.
What should my server DNS BE?
Public DNS Servers
Your home router is likely set by default to use your ISP’s DNS servers, which may or may not be very reliable. There are a number of third-party DNS servers available as well. Personally, I prefer OpenDNS (208.67. 220.220 and 208.67.
What primary DNS should I use?
Public DNS Servers
Personally, I prefer OpenDNS (208.67. 220.220 and 208.67. 222.222) and Google Public DNS (8.8. 8.8 and 8.8.
What happens if primary DNS down?
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). Distributes the load between primary and secondary servers.
Is Primary DNS the same as IP address?
An IP address is an address assigned to any computer (including servers) to identify it on a given network. A DNS address is a Domain Name Service which is used to convert alphabetic references into a server’s IP address generally for hosting services. An example of a DNS name is “ns1.godaddy.com”.
How much is a DNS server?
|Managed Zones*: 0-25||$0.20 per managed zone per month.|
|Managed Zones*: 26-10000||$0.10 per managed zone per month for each additional zone after 25.|
|Managed Zones*: over 10000||$0.03 per managed zone per month for each additional zone over 10000.|

What is the difference between a primary DNS zone and a secondary DNS zone?
Primary DNS zone is hosted in the Primary DNS Server. Secondary DNS Zone: A Secondary DNS Zone is Read-Only copy of a Primary Zone, or another Secondary Zone, kept in a Secondary DNS Server. A Secondary DNS Zone is used to reduce the load on Primary DNS Servers and also for preventing single point of failure.
What is the difference between primary and secondary DNS server?
Primary servers get this information directly from local files. Secondary servers contain read-only copies of the zone file, and they get their info from a primary server in a communication known as a zone transfer. Each zone can only have one primary DNS server, but it can have any number of secondary DNS servers.
