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 you have two different domain controllers on the same network?
4 Answers. The two domains will not interfere with each other on the same network. There will be no trust established between them unless you manually establish one. Assign only one domain’s DNS servers via DHCP.
Can a DNS server be primary and secondary for the same zone?
Only one DNS server should be configured as primary for a zone, but you can have any number of secondary servers for redundancy. Both primary and secondary servers for a zone serve exactly the same data to clients. Because of this you could easily “simulate” a secondary server on a single computer with 2 IP addresses.
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.
How many primary domain controllers are there?
As a rule of thumb, if you have 10 or less computers then a Workgroup is advised. Over 10 a Domain is recommended. Typically you would want two domain controllers, one acts as a back up and should be physically separate from the other, i.e. Don’t have both in the same VM Host.
Why have a secondary domain controller?
The reason why businesses should invest in both a secondary Domain Controller and backups is simple. In addition to being able to restore a failed DC fast thanks to a reliable and recent backup, a secondary DC will be able to keep things running even when one has failed.
Can you have more than one domain controller?
2 Answers. The primary reason for having multiple domain controllers is for fault tolerance. They will replicate the Active Directory information between them and can provide services if the other is unavailable. Having multiple DC’s is a best practice standard.
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.
How do I setup a primary and secondary DNS?
Log in with your password, and then choose “Manual Internet Connection Setup.” Fill in the DNS server fields with the primary and secondary DNS addresses. Open the Google Wifi app, go to the settings tab, then pick “networking & general.” Tap on advanced network, and then DNS.
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”.
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.
What is the difference between primary and secondary DNS?
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.
How do I setup a secondary DNS server?
First, open up DNS Manager in AS-DNS001 (the server where we will create a secondary zone) by going to Server Manager and select Tools > DNS. In the DNS Manager, expand the server name. You’ll see a few items with icon similar to a folder, including Forward Lookup Zones and Reverse Lookup Zones.
