Question: Should I Have 2 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 would you have multiple DNS servers?

You want more than one of each ideally. DNS is a replicated system, with DHCP how much config you have to do depends on your version of Windows but you can have multiple DHCP servers – it’s called “split scope”. So both servers are aware of each other and can provide addresses to clients across the full IP range.

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 is every DNS domain required to have at least two 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.

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.

Why would you activate more than one NIC?

If a NIC fails, it could potentially sever an important connection. One way to lessen the potential for these problems is to install two or more NICs in network servers. Using multiple NICs offers these key benefits: Load balancing.

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 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.

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.

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”.

Should DNS servers point to themselves?

Ideally it would point to itself in the network settings for dns. In the Dns server role setup you should put in the forwarders that the server will use for any dns queries outside the local LAN. So here you can use googles or your ISPs Dns servers.

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.
