Why do I have two DNS servers?

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.

Should I have 2 DNS servers?

Secondary DNS servers are not mandatory—the DNS system can work even if only a primary server is available. But it is standard, and often required by domain registrars, to have at least one secondary server.

Can I use 2 DNS at the same time?

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).

Why do I have so many DNS servers?

Many ISPs have their own DNS servers. Different public DNS servers offer different filters on the sites that they support. Some servers will not support access to sites that are age restricted. Others may impose other restrictions.

Which DNS server is fastest?

These start with performance, and independent testing from sites like DNSPerf shows Cloudflare is the fastest public DNS service around.

Does changing DNS affect anything?

Although DNS is not directly related to your Internet speed, it can influence how fast an individual webpage appears on your computer. Once a connection has been established though, it should not affect download speeds. If you want to amend your router’s DNS servers however, this can help improve your overall speed.

Can you mix and match DNS servers?

Yes you can set several. Different dns clients & servers work differently but mostly they’ll use the one with the best latency.

Can you have 2 domains with same IP?

You can indeed host many many websites on the same IP address. Though, if you want your website to use secure HTTP (HTTPS), then you have to use a unique IP address for that web site only.

How many DNS servers should my WIFI have?

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 happens if you have 2 DHCP servers?

Because two DHCP servers cannot serve the same addresses, address pools defined for a subnet must be unique across DHCP servers. Therefore, when using two or more DHCP servers to serve a particular subnet, the complete list of addresses for that subnet must be divided among the servers.

How do I know if my DNS is poisoned?

So how do you detect a DNS cache poisoning attack? Monitor your DNS servers for indicators of possible attacks. Humans don’t have the computing power to keep up with the amount of DNS requests you will need to monitor. Apply data security analytics to your DNS monitoring to discern normal DNS behavior from attacks.

Can DNS affect gaming?

DNS improves the gaming experience for users via its speed and high-security nature. It improves latency and reduces ping, allowing gamers to enjoy their activities and minimize lag issues. DNS also reduces packet loss, enables wider customizability with websites, and eliminates jitter.
