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?
Thanks for answering! I was more wondering what kind of issue DNS solved and why it was solved that way. Also if anyone thought of another solution.
I also read the history here (https://cyber.harvard.edu/icann/pressingissues2000/briefingbook/dnshistory.html), and it still seems pretty sketchy to me that the concern of website names being inaccessible to small businesses and such was solved with the ICANN. Didn’t this just make domain names into stuff you could speculate with? I may be tweaking rn, but I don’t think it’s necessarily right.
The issue DNS solves is the same as the phone book. You could memorize everyone’s phone number/IP, but it’s a lot easier to memorize a name or even guess the name. Want the website for walmart? Walmart.com is a very good guess.
Behind the scenes the computer looks it up using DNS and it finds the IP and connects to it.
The way it started, people were maintaining and sharing host files. A new system would come online and people would take the IP and add it to their host file. It was quickly found that this really doesn’t scale well, you could want to talk to dozens of computers you’d have to find the IP for! So DNS was developed as a central directory service any computer can request to look things up, which a hierarchy to distribute it and all. And it worked, really well, so well we still use it extensively today. The desire to delegate directory authority is how the TLD system was born. The host file didn’t use TLDs just plain names as far as I know.
I understand. Thank you!
