Why You Should Know Your Sites Name Servers

How to Change DNS Nameservers for a Domain Name

You dont need to know your websites name servers, but it could be useful in the future. If you register a domain and purchase hosting from the same company, you can safely ignore your name servers without too many issues. If you switch, or if you register apart from your hosting, youll need to have your name servers handy.

How Long Does It Take For Nameservers To Update

Anytime you change DNS records, it takes time for the update to take effect across the internet. This is called DNS propagation, and it can take up to 48 hours.

Changes can be seen soon after you update, but it could still be updating in other regions. So allow up to 48 hours for your nameservers to propagate fully.

You can check the status of your update on tools like DNSchecker.org.

Nameservers are an integral part of the domain name system. Without them, youd have to memorize an IP address for every website you visit.

Knowing what a nameserver is helps you better navigate the internet, but it can also help you manage your website.

Whether you need to point your domain name toward your web hosts nameservers or you want to set up a private server, nameservers help you direct traffic to your website.

You can easily find and change your nameservers with Bluehosts DNS manager or on whatever registrar youre using. If you do decide to set up a custom server in Bluehost, use a nameserver checker to do a DNS lookup and make sure theyre pointed to the right place.

Domain Management: How To Update Nameservers

Domain Name System is the system that translates a domain name into an IP address. DNS forms the foundation for the Internet. DNS records are used to map each web service to the correct server. Each domain name has a collection of DNS records called a zone file. A Nameserver is a computer where DNS Records are stored. Domains will utilize the DNS records of the name server that they’re pointing to. A more in-depth look at DNS Records.To learn how to update your Nameservers, please follow the steps below and click image to enlarge:

    The Domain Name System

    So how does your computer find a computer at google just from google.com?

    You need a phone book.

    When your computer is trying to find a computer at google.com it looks up the correct IP Address using the Domain Name System .

    Its these phone book entries that SquareSpace needs you to configure. You need to tell everyone who looks up the phone book that yourdomain.com should point to a computer at SquareSpace.

    This phone book has some nice features that are suitable for a global internet. Ill try to get to those. But ultimately its a list of domain names and the relevant IP addresses of computers so that other computers can look that information up.

    We call these phone books a Name Server or just nameservers.

    How To Find Your Nameserver In Bluehost And On The Web

    Domain Name System

    Log in to your Bluehost account and go to the Manage button on your sidebar. In that menu, click DNS and then go to the Name Servers section.

    The Different Types Of Dns Server

    Once a DNS query is entered, it passes through a few different servers before resolution, without any end user interaction.

  • DNS recursor
  • This is a server designed specifically to receive queries from client machines. It tracks down the DNS record and makes additional requests to meet the DNS queries from the client. The number of requests can be decreased with DNS caching, when the requested resources are returned to the recursor early on in the lookup process.

  • Root name server
  • This server does the job of translating the human-friendly host names into computer-friendly IP addresses. The root server accepts the recursors query and sends it to the TLD nameservers in the next stage, depending on the domain name seen in the query.

  • Top Level Domain nameserver
  • The TLD nameservers are responsible for maintaining the information about the domain names. For example, they could contain information about websites ending in .com or .org or country level domains like www.example.com.uk, www.example.com.us and others. The TLD nameserver will take the query from the root server and point it to the authoritative DNS nameserver associated with the querys particular domain.

    What Is A Dns Ns Record

    NS stands for nameserver, and the nameserver record indicates which DNS server is authoritative for that domain . Basically, NS records tell the Internet where to go to find out a domains IP address. A domain often has multiple NS records which can indicate primary and backup nameservers for that domain. Without properly configured NS records, users will be unable to load a website or application.

    Here is an example of an NS record:

    How Does Domain Name For Servers Work

    Do you ever go in-depth and analyze the site? Yes! Then you might know that every site has two name servers ns1 and ns2 to which a domain is pointed. They are presented with the hosting package you buy from the web host along with the hosting account.

    ns1 = primary server

    ns2 = backup server

    Similar to the process of devices like a phone in which the phone is connected to a network. Just like this, your computer is also connected with a wireless network connection. So, when you want to reach any site, you have to first enter its domain name in your web browser.

    For example, if you type any URL in your system browser, your system goes to the domain registrars and requests the name servers for your searched domain name. Then, the name server requests the IP address for your domain servers name and finally gets the desired site.

    Domains And Ip Addresses

    What is Name Servers? & How to Change Name Servers of Domain?

    If you type a domain like google.com in your web browser and hit enter Googles web page appears.

    Your computer has reached out and asked a computer at Google for the website. Google sends back the website and your browser displays it.

    The crucial thing to know here is that the internet doesnt actually use the domain google.com to talk to the computer! The internet uses numbers to identify every computer or device on the internet. Ill explain how your computer turns google.com in to a number later on.

    You have seen examples of a number used to identify a computer in the SquareSpace settings above – 198.185.159.145.

    We call these numbers IP Addresses. IP stands forinternet protocol but that doesnt matter too much here. Just remember the computers on the internet actually use numbers to identify each other, not the domain.

    Your phone has its own unique IP address, your computer has an IP address. Your telly probably has an IP address these days. If you have a smart fridge it also has an IP address. Every device or computer on the internet needs an IP address number to work.

    In fact a serious issue right now is that were running out of numbers for all the things as the internet keeps growing! Blocks of those numbers are like gold to companies like Google or Amazon.

    How Does A Web Page Appear In A Browser

    Everything thats connected to the Internet websites, computers, laptops and other devices, have an IP address made up of numbers. But IP address is a string of numbers and is difficult to remember, so to make them easier for humans, domain names are used instead, to reach websites as they are easy to recognize and remember. So, it is the domain name that you enter into a web browser in order to reach a specific website and this is how a web page appears.

    All the information of domain names including registration information, emails, addresses of web host is stored and managed by domain name system. Domain name servers control different aspects of domain name with the help of different elements- nameservers, A zone file, Records, CNAME and other elements.

    All elements are important but in this post, we will discuss about domain name servers-the GPS system of the computer in online world.

    Where Are Your Domain’s Nameservers Located

    When you register your domain through a domain registrar, your domain is usually first pointed to your domain registrar’s nameservers.

    Your domain registrar is the place where you can edit your domain’s nameservers. If you want to use these nameservers, edit your DNS records to point your domain name towards your hosting provider.

    But experts suggest that you should use the nameservers provided by your web hosting. However, it depends upon your requirements and needs.

    What Is A Domain Name Server

    A DNS is a computer server that contains a database of many IP addresses and their associated domain names. It serves to translate a requested domain name into an IP address, so that the computer knows which IP address to connect to for the requested contents. The Internet is a network of connected computers, and they communicate with each other through IP addresses. A DNS plays an important role in helping us to conveniently use the Internet and it is one of the most essential foundations of the Internet as we know it today.

    It is much easier for us to remember a domain name, webnic.cc, rather than a string of numbers, 104.20.73.209 to WebNICs website. Both the domain name and the DNS are extremely important and they work together to make this possible. Read our blog here if you are unsure what is a domain name.

    A great example is to see a DNS as a phone book, which matches a name to a telephone number. You can search for the name you want and find the corresponding phone number. It is also a similar concept to your smartphones contact list, which will match a contact name to a phone number. Remembering domain names is definitely easier for us than to remember a string of numbers. DNS helps us to do this by match domain names to IP addresses, and simplifies our web surfing experience significantly.

    Disadvantages Of Domain Name Server

    Some disadvantages of DNS are:-

    Can be hacked:

    Stops internet:

    Suppose DNS servers get a virus attack then the websites associated with the DNS server also not loads. This is a very dangerous issue because if thousands of websites stop working then the business of the website owners is damaged.

    Controlled by one organization:

    All the DNS servers are controlled by ICANN. ICANN is a non-profit organization. The organization belongs to one country. If any rules and regulations of the country change then ICANN responsibility may also change.

    Incorrect names:

    There exist some hackers who own similar domain names to popular websites. They purchase similar domain names and fool the people and get benefits from them. If any user types by mistake any similar domain of a popular website then the user goes to the wrong website which looks the same as the original website. Then that website gets important information from you e.g. get login details from you.

    Error handling:

    It is difficult to troubleshoot the DNS server. If any error occurs in the DNS server then fixing it is a difficult process. This is because all the DNS servers are connected.

    Master-slave relation:

    The DNS servers work in a master-slave manner. One DNS server acts as a master to other DNS servers. Main DNS servers guide other DNS servers. If the master server fails then other DNS servers also become unresponsive. This is because they cannot forward their response to the master server.

    Summary Of The Dns Process

  • DNS Query – a web browser or other application requests a human readable hostname such as www.example.com. The query is handled by the DNS Resolver, which is responsible for finding the IP matching the hostname.
  • DNS Root Servers – the Resolver talks to a Root Server and is referred to a Top Level Domain Name Server, corresponding to the TLD in the query, such as .com.
  • TLD Name Server – the Resolver contacts the relevant TLD Name Server and is referred to an Authoritative Name Server that holds the current details for the domain name.
  • – finally, the Resolver sends the query to the Authoritative Name Server which is is responsible for that domain . This DNS server knows the IP address for the full domain, www.example.com, and returns that answer to the DNS Resolver.
  • DNS Query Resolved – now that the DNS Resolver knows the IP address for the domain name, it returns it to the browser or other application on the client side. The client can then connect to the server using the IP address, and start communicating with it.
  • Client Can Communicate with Server – If the client is a browser, and the user typed in a domain, the website at that domain can now be displayed. If the client is a messaging app, the user can now send messages to other users via the server.
