DNS for various domain aliases is broken

[lilyball]

We appear to have a few domain aliases for www.rust-lang.org other than rust-lang.org. The ones I'm aware of are rust-lang.com, rust-lang.net, rustlang.com, rustlang.org, and rustlang.net. There may be others too, I haven't gone looking.

The DNS for some of these is ok and for others it's broken. "Broken" means that visiting the page takes you to the easydns.com parked domain page.

Via dig, it seems that the correct domains all have an A record for 72.8.141.90, which is the IP for fwd.st2.easydns.com. These correct domains are rust-lang.net, rustlang.com, rustlang.net, and of course rust-lang.org. These all get redirected to www.rust-lang.org.

Unfortunately, others have 216.220.40.248, which is the parked domain DNS. The bad domain here is rust-lang.com.

You'll note I haven't mentioned rustlang.org yet. That's because it actually has both A records. This means that a visitor may arbitrarily either get redirected correctly, or may see the parked domain page. I personally can get both, by using different browsers.

So in short, the DNS for the following domains needs to be fixed to use the correct A address: rustlang.org, rust-lang.com.
