login.yahoo.com is a nickname for login.yahoo.akadns.net
login.yahoo.akadns.net has address 216.109.127.60

Looks like they are both defined :) 

Does this happen with all browsers? Or just one browser?  Could it be that the 
browser or some plugin is doing something behind your back. IE they must have 
meant this and are a standard user and figured everything on the web needs to 
have www in front of it.   The reason I ask is you say the same thing works 
for every site. So that makes me think something else is doing something 
funny.  Ie if I look at my website.  Http://patrick.muldoon.us/ resolves.  
while http://www.patrick.muldoon.us/ comes up with not found. If you where to 
go to those sites, do both work?  

The reason the real name was asked for is we could query dns to give you a 
better answer as opposed to wildly speculating (Which can be fun, but 
sometime not very productive). 

Also do you have any wildcards in your dns zone?  

Hope this helps,
