An unusual dns question

[Chris Meyer]

This makes sense since 443 is the port that https traffic travels on.

As to why Windows knows to try that first whereas Linux just fails, I 
couldn't say. Although on my 7.3 box it also works when you insert 
"https://" instead of "http://".... My guess would be that since the 
page lets you create an account and pick a password they've rather 
intelligently decided it should be encrypted.
