How many DNS servers should I have?
two DNS serversAt 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.
Which Google DNS is faster?
According to the company, the service is faster than both Google DNS and OpenDNS. CloudFlare’s DNS uses 1.1. 1.1 and 1.0. 0.1 for IPv4 connections (or 2606:4700:4700::1111 and 2606:4700:4700::1001 for IPv6), so it’s pretty easy to remember.

Is it safe to use 8.8 8.8 DNS?
From the security point of view it is safe, dns is unencrypted so it can be monitored by the ISP and it can of course be monitored by Google, so there may be a privacy concern.
Why do I have 2 DNS servers?
8 Answers. The major point in having a secondary DNS server is as backup in the event the primary DNS server handling your domain goes down. … A secondary DNS server is always up, and ready to serve. It can help balance the load on the network as there are now more than one authoritative place to get your information.
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 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. … Every major DNS service has at least primary and secondary servers to ensure that requests will always be answered.
What causes DNS to fail?
Typically, DNS errors are caused by problems on the user end, whether that’s with a network or internet connection, misconfigured DNS settings, or an outdated browser. They can also be attributed to a temporary server outage that renders the DNS unavailable.
Can a Cname point to another domain?
CNAME records must point to another domain name, never to an IP address. A hostname defined in a CNAME record must have no other resource records of other types (MX, A, etc.), except for DNSSEC records like RRSIG and NSEC.
Can an A record point to two IP addresses?
Yes you can have multiple IP’s for the same A record. There’s a few problems with this if used for redundancy purposes… DNS servers and DNS resolvers randomly choose the order of the list of IPs – even though you might configure it a certain way on your DNS Server hosting the zone, resolvers will flip it.
