DNS is the “domain name system.” It translates human-friendly website addresses like if you’d like to verify this.
Every computer, Web server and networking device on the Internet has one of these numerical IP addresses.
In some cases, through a process called “network address translation,” a whole house, office or building shares the same IP address.
Your local name server is like the little address book that you kept near the telephone before mobiles were invented.
If you hired A1 Triple Glazing to retrofit your windows, you might have copied their phone number into your address book.
The next time you had to ring them, the number would be right there, immediately available. The name servers just “know.” Every domain name like .
Imagine that your biggest client calls because they are having trouble retrieving their email. You can hardly reply, “No problem, I’ll get back to you in 24 to 48 hours.” And yet DNS gets away with it!
Or they want to know what their best-selling item is right now. If you need to move a website or change the way a domain’s email is handled, you’ll be faced with a vague 24 to 48-hour delay.
This is quite an anomaly in a world of ultra-convenience and super-fast everything.This article explains what DNS is, how it works, where that pesky delay comes from, and a couple of ways to work around it.Instead, the task is shared by millions of name servers (also spelt as one word, “nameserver”), which constantly refer to and update each other.Every computer connected to the Internet has a name server.When you attempt to visit a website like in this case.Your computer’s name server can’t make this translation by itself; it has to keep asking other name servers until something somewhere comes back with a definitive answer.
