How do DNS Root Servers work?
A root name server is a name server for the root zone of the Domain Name System (DNS) of the Internet. It directly answers requests for records in the root zone and answers other requests by returning a list of the authoritative name servers for the appropriate top-level domain (TLD).
How do I make my own DNS server?
You need to add at least two “nsX.domain.com” entries, but they can both point to the same IP. Delegate your domain to the names you just created. At NameCheap, you would go General > Domain Name Server setup, and Specify Custom DNS Servers. Then, enter the two (or more) names you just created “nsX.domain.com”.

How many DNS root servers?
A common misconception is that there are only 13 root servers in the world. In reality there are many more, but still only 13 IP addresses used to query the different root server networks. Limitations in the original architecture of DNS require there to be a maximum of 13 server addresses in the root zone.

What is DNS AAAA record?
An AAAA record maps a domain name to the IP address (Version 6) of the computer hosting the domain. An AAAA record is used to find the IP address of a computer connected to the internet from a name. For example, all the DNSimple name servers are assigned to an IPv6 address and can be queried via either IPv4 or IPv6.
Where are the DNS root servers located?
Root name servers are the servers at the root of the Domain Name System (DNS) hierarchy. The DNS is the system which converts Internet domain names, such as www.netnod.se, into numeric addresses such as 212.237. 144.84 or 2a07:2180:0:1::400.

How many DNS servers should I 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.
Why don’t we maintain our own DNS?
Why do we need a Domain Name System? Domain Name System allows users to have the same url or consistent domain name while IP addresses change frequently. We need DNS because without it users would need to keep on checking the IP addresses of others and of themselves to send messages or view sites.
Is a name server a DNS server?
DNS (Domain Name System) actually saves your website name and corresponding IP address to where the website is hosted. A name server is the server where DNS software is installed and manage all the domain name records. Name servers are often called DSN (Data Source Name) servers.
What is DNS in networking?
Domain Name Servers (DNS) are the Internet’s equivalent of a phone book. They maintain a directory of domain names and translate them to Internet Protocol (IP) addresses. This is necessary because, although domain names are easy for people to remember, computers or machines, access websites based on IP addresses.
Why is Cloudflare bad?
If you don’t have smart caching on or your server is relatively low power – particularly shared servers – then your site might end up crashing entirely. So, Cloudflare protects your site by filtering out bad requests and only referring the good requests, which allows your server to respond much more quickly.
Why you should not use Cloudflare?
They block IP addresses at ISP level to prevent their citizens from downloading copyrighted content for free. That led to a lot of sites being banned accidentally, but also to a lot of websites using Cloudflare being partially removed from the British Internet!
Why is Cloudflare free?
