Essentially, after renting some space from your web hosting company, only this company and you know where your web site is hosted. Nobody else has this key information. Even more important, the company your hired to provide this information to the rest of the Internet (the registrar you hired to provide Domain Name Service – see Step 1) does not know about your hosting decision. You have to inform them.
In most cases, the registrar has some administrative interface to help them in this. In the case of the registrar I selected for my own lexyk.com domain, Gandi.net has such an easy administrative interface. They need to know where to find the right DNS information. This is the data that was provided to us at the end of Step 2.
So, I informed Gandi.net of the primary and secondary source of DNS information (
ns.ovh.net for OVH.com, the hosting company I’ve choosen for the web site of this tutorial: Lexyk.com). After providing this information, it’s only a matter of time and patience. As you may imagine, there are millions of computers to inform. This is done by the DNS protocol which will help distribute the information around the world. Generally, this take 24 to 48 hours. It may be faster in some cases, but your mileage may vary. You are a few hours from having your web site visible throughout the global Internet.
