Key points of this
- It’s a system.
- Manage the association between IP addresses and domain names
- Convert IP addresses and domain names
- It stands for “Domain Name System.”
I’ll write it simply.
What is DNS ?
A system that acts as an intermediary between humans and computers regarding online address notation.
and
A system that ties IP addresses to domain names
DNS (Domain Name System) is a system that manages internet addresses. Humans use domain names (like example.com) to access websites, but computers use numeric IP addresses (like 198.51.100.2) for communication. DNS connects these domain names to their corresponding IP addresses, allowing computers to find the correct location when you enter a domain name.
A Bit More Detail
- IP Addresses and Domain Names
- IP Address: A numeric address used by computers on the network (e.g., 198.51.100.2).
- Domain Name: A user-friendly address (e.g., example.com) that is easier for people to remember.
- Why It’s Needed
- Computers only understand IP addresses, but domain names are easier for people to remember. DNS serves as the bridge between the two.
- How It Works
- Enter Domain Name: When you visit a website, you type in a domain name (e.g., example.com).
- DNS Server Converts: The DNS server looks up the domain name and provides the corresponding IP address (e.g., 198.51.100.2).
- Access Website: Your computer uses the IP address to connect to the website.
Summary
DNS is a system that translates website names into their corresponding IP addresses, enabling computers to locate and connect to the correct websites when you use domain names.
