Every day, millions of people visit websites, and it appears to be so simple. In reality, a few clicks on your laptop initiate significant work before the site is even launched.
Here, we'll tell you about DNS and domains and why you need an IP address. And what does all this have to do with the A record? To answer these questions, we need to dig deeper into the Domain Name System (DNS) and why it's needed in the first place.
It's better if we compare it to something we use in real life. The Domain Name System is like a telephone book, with each site having a unique "number". When a user types in a site name, the computer asks the DNS what "number" that site has, then "calls" that "number," and you end up with a page in your browser.
This process actually resembles our phone call, but that's not exactly true. The "number" is the IP address of the site. An IP address is assigned to everything on the Internet. This address is needed to find the corresponding Internet device - just as a home address is used to find a specific person anywhere in the world.
For Internet devices, an IP address looks like a set of numbers separated by dots. It is not easy to remember all the numbers for all the websites we use. Numbers are great for machines, but for humans, it's much easier to work with words. That's why we type words in the address bar instead of numbers. These words are called domain names. Now that you know the terminology, it's easier to see the big picture.
All websites have IP addresses and Domain Names. This information resides in the Domain Name System (DNS) and exists as an 'A record'. The 'A record' links the domain name to the IP address of the server hosting our website. In a few words, to find the IP address of a server on the Internet, the DNS server initially queries the first address. And in case it has an A record with our domain name - and IP address will be returned.
In the 'A record,' the 'A' stands for address. Whenever you visit a website, send an email, connect to Instagram or Facebook, or do almost anything else on the Internet, the Address you enter is a series of words connected by dots.
'A' entries have multiple implications. You can use various 'A-records' for the same domain to provide redundancy. Alternatively, multiple names may point to the same address, in which case each name will have its own 'A Record' pointing to the same IP address. 'A Records' points your domain to the hosting of your site.
When you plan to create a website or personal blog, one of the first things you'll need is a domain name. It should be catchy and memorable to people, and it should be unique. Nowadays, registration has become a straightforward process.
- Check the availability of the domain.
- Order and complete the domain registration.
- Confirm ownership of your new domain name.
Of course, this sounds pretty simple, but some of you may still be unsure if you can do it independently. In that case, our team is not only ready to create a website for you but will also be happy to help you with obtaining a domain name for it.
