This site actively determines the DNS servers that your computer uses by observing how your DNS requests are processed on the internet.

DNS records types A. The A (address) entry is one of the key DNS records. It is needed to connect the domain with the server IP address. Until the A-record is registered, your site will not work. When you enter the name of the site in the address bar of the browser, it is by the A-record that the DNS determines which server to open your site. For example, one IP address of Google.com is 74.125.142.147.If you were to type this IP address in the Reverse DNS Lookup Tool, it will return the host name of Google as listed in the database of the Address and Routing Parameter Area (ARPA) top-level domain of the Internet.

The private DNS hostname takes the form ip-private-ipv4-address.ec2.internal for the us-east-1 Region, and ip-private-ipv4-address.region.compute.internal for other Regions (where private-ipv4-address is the reverse lookup IP address). You can use the private DNS hostname for communication between instances in the same network, but we can't. Whatsmydns.net lets you instantly perform a DNS lookup to check a domain name's current IP address and DNS record information against multiple nameservers located in different parts of the world.

What is a DNS Server?

When you browse to a URL (website address), the DNS server tells your web browser where to go (the address on the internet where that website is found).

Why should I care?

When you want to go to your bank's website, you want to go to the real bank website and not a fake bank website created by a hacker. If you unknowingly use a DNS server that's run by a hacker, it could redirect your browser to phony and dangerous websites.

What determines which DNS server my computer uses?

There are several settings that determine which DNS server your computer will use:

• Your DNS server can be configured in the network settings of your Operating System.
• If you don't configure DNS in your Operating System, then you can set it in the router.
• If you don't set it in the router, then your ISP decides which DNS server you use.

This is how things are supposed to work. Unfortunately, there are things that could possibly go wrong:

Fruity Loops can be used on its own as a complete package, or in combination with a digital recording program like Cakewalk, Cubase, etc. Complex songs and sweet drum loops can be created with a few clicks, and the resulting song or loop can be exported to a WAV or MP3 file, and MIDI can be exported to a standard MIDI file.

• Malware on your computer or router could cause your computer to use a rogue DNS server.
• Different entities can hijack and redirect how your DNS requests are processed. These entities may have different motives for doing this and can include hackers, your ISP or even a government agency.

How does 'What's My DNS Server?' help?

'What's My DNS Server?' actively observes how DNS requests from your computer are resolved and then shows you which DNS server on the internet was used and whether any issues are known about it. You can then verify that the DNS server that you believed was being used was indeed used.

Is there anywhere else where I can get this functionality?

Yes! RouterCheck is a tool that allows you to easily scan your home network for security issues. It not only looks at DNS health, it also checks many other aspects to determine the overall security and privacy of your network. The technology that runs 'What's My DNS Server?' is built into RouterCheck along with many other advanced features.

What Is DNSSEC?

• A DNS server – short for Domain Name System server – converts web addresses into IP addresses.
• Without a DNS server, you won't be able to connect to any websites.
• If you're having issues with your default DNS server, you can change it.

A Domain Name System (DNS) server is a fundamental part of the backbone of the internet - without it, it would be impossible to use a web browser to find websites.

You can think of the DNS server as a phone book. When you ask your computer to load a website, the DNS server matches the website's name with the right IP address. This lets your computer find and load it properly.

How does a DNS server work?

When you enter a URL, what you're really doing is asking your computer to find and connect to another IP address. To do this, it uses a set of related servers, all of which form the DNS server:

• The DNS recursive resolver
• The root nameservers
• The TLD nameservers
• The authoritative nameservers

Here's how it works.

The DNS process, step-by-step

1. You ask your web browser to load a website. Since computers don't speak English, your browser can't read a name like 'www.insider.com' and instead needs an IP address. Because of this, it sends your request to a DNS recursive resolver. The DNS recursive resolver's goal is to find the IP address connected to the website you entered.

2. The resolver's first step is to find the website's 'Top Level Domain' or 'TLD' - in other words, whether it's a .com, .net, .org, or another type of site. It does this by asking the root nameserver, which keeps a list of every website in each TLD.

3. Once the resolver knows the TLD, it goes to the corresponding TLD nameserver (for example, the .com nameserver) and asks it to find the right IP address.

4. The TLD nameserver finds the IP address and hands it off to the authoritative nameserver, which will figure out if that address is correct.

5. The authoritative nameserver sends a message to the address and waits for a response - if it gets the right response, then it has the right IP address for the website you want.

6. If the IP address is correct, the authoritative nameserver sends it back to your web browser.

7. Once your web browser receives the right IP address, your webpage starts to load.

All this happens in a matter of seconds - if your internet is very fast, or you've visited the website recently (see below for more information), it can happen in milliseconds.

Caching can avoid calling the DNS server

If you're visiting a new website, your browser will go through the entire process outlined above. But if it did this for every single website, things could get slow - that's why websites you've visited recently are stored in your web browser's cache.

When you try to load a website, the DNS server will first check your cache to see if the IP address is already saved there. If it is, it'll retrieve the IP address directly from the cache, which saves time.

Each entry in the cache has a time limit associated with it, referred to as the TTL (time-to-live). The TTL for any IP address is generally about 48 hours, and once that passes, the IP address will disappear from your cache. This means that the DNS server will have to go through the whole recursive search process again.

Changing your DNS server

Find Dns Server

As a general rule, your web browser uses a standard, public DNS server, usually configured and maintained by your internet service provider.

Some advanced users manually change their DNS server, though. This can boost your internet speed and protect your privacy.

Changing your DNS can be done via your computer's 'Network' menu, in the Settings app. If you're looking for a new DNS, you can try the Google Public DNS or any number of other custom DNS servers.
