When you open a website, many networking components work together in the background. IP address, DNS, and domain names are key parts of how cloud-based websites are accessed. This article explains these terms in simple words.
What is an IP Address?
An IP address is a unique number given to a server or device connected to the internet. It works like a house number that helps data reach the correct destination.
Every cloud server has an IP address.
Why IP Address Is Important
Computers and servers use IP addresses to identify and communicate with each other. Without IP addresses, data cannot reach the correct server.
What is a Domain Name?
A domain name is a human-friendly name used to access a website. Instead of remembering numbers, people use domain names.
Example: A website name is easier to remember than an IP address.
What is DNS?
DNS stands for Domain Name System. DNS converts domain names into IP addresses that computers can understand.
It works like an internet phone book.
How DNS Works
When you type a website name in your browser, DNS finds the matching IP address of the server and connects you to it.
How IP Address, DNS, and Domain Work Together
- User enters a domain name in browser
- DNS looks up the IP address
- Browser connects to the cloud server using the IP address
- Website content is displayed
Role in Cloud Computing
In cloud computing, servers may change or scale. DNS helps connect users to the correct cloud server without changing the domain name.
Simple Real-Life Example
Think of a contact name in your phone. You dial the name, but the phone uses the actual number. Similarly, you type a domain name, but the internet uses the IP address.
Why These Concepts Matter
Understanding IP address, DNS, and domain names helps beginners understand how websites and cloud applications are accessed.
Final Conclusion
IP addresses identify servers, domain names make access easy, and DNS connects both. Together, they form the foundation of cloud networking.
Knowing these basics makes cloud computing easier to understand.
