what’s up with DNS?

I never understand why, having such a victimable system as DNS, Internet is still alive. Now my understanding is giving up.

Yesterday I decided to read a bit of Joel. I selected his site from the bookmarks, but got a standard site of cybersquatters instead of Joel's site. I was surprised how Joel can lose his domain and looked up whois for details. And all was ok in it. After some investigations, I worked out that all is wrong with DNS:

$ host -a JOELONSOFTWARE.COM 195.19.225.253
Trying "JOELONSOFTWARE.COM"
Using domain server:
Name: XXX.XX.XXX.XXX
Address: XXX.XX.XXX.XXX#53
Aliases: 

;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 17444
;; flags: qr rd; QUERY: 1, ANSWER: 2, AUTHORITY: 1, ADDITIONAL: 1

;; QUESTION SECTION:
;JOELONSOFTWARE.COM.            IN      ANY

;; ANSWER SECTION:
JOELONSOFTWARE.COM.     99777   IN      A       83.222.5.155
JOELONSOFTWARE.COM.     99777   IN      A       83.222.5.156

;; AUTHORITY SECTION:
COM.                    99952   IN      NS      3sistersmassage.COM.

;; ADDITIONAL SECTION:
3sistersmassage.COM.    20771   IN      A       216.127.88.131

Received 114 bytes from XXX.XX.XXX.XXX#53 in 39 ms

where "XXX.XX.XXX.XXX" is the provider's DNS server.

Look at the "AUTHORITY SECTION". The value "COM." is ridiculous! How can it be? Is it possible to spam DNS now? Why not to fake a site IP for Microsoft Passport?

I'm afraid soon we'll upgrade Internet. E-mail is spam, and DNS smells danger.
