I thought it would be cool to have my own TLD, but apparently it’s all managed by the ICANN, so you can’t just name your website with any TLD you want. There are different prices. But at least you can customize your second level domain. Why aren’t TLDs like this?
In case you didn’t know, domain names form a tree. You have the root
., you have TLDscom., and then usually the customer’s domaingoogle.com., then subdomainswww.google.com.. Each level of dots typically hands over the rest of the lookup to another server. So in this example, the root servers tell you go ask .com at this IP, you go ask .com where Google is, and it tells you the IP of Google’s DNS server, then you query Google’s DNS server directly. Any subdomain under Google only involves Google, the public DNS infrastructure isn’t involved at that point, significantly reducing load. Your ISP only needs to resolve Google once, then it knows how to get*.google.comdirectly from Google.You’re not just buying a name that by convention ends with a TLD. You’re buying a spot in that chain of names, the tree that is used to eventually go query your server and everything under it. The fee to get the domain contributes to the cost of running the TLD.
