Hi, professional DNS engineer here! if anyone has any questions about the inner workings of DNS or top level domains, ask away! (THIS IS MY MOMENT)

So why do we need the .com or .org or whatever at all? And the www. as well?

I remember when I had to type the whole http://www.cakefarts.com and now just cakefarts.com works. What changed? And what's next?

To answer your other question: most likely, www.cakefarts.com is now accessible from cakefarts.com for one of three reasons:

  1. Your web browser automatically checks the A record "www" if "cakefarts.com" doesn't have an A record. A records are the records in a DNS server that says "this domain goes here"
  2. The site cakefarts.com put their website on cakefarts.com and placed a CNAME record called "www" that points to cakefarts.com
  3. cakefarts.com has an APEX record that points to www.cakefarts.com

For the 'record', www is just a really common record name. There's nothing special about it. You could have dudebro.cakefarts.com or wwwwwww.cakefarts.com. It's up to the domain owner.
