mail.yahoo.com, "missing A records" and squid proxy

  • From: Jim Mercer

we have a squid proxy set up as transparent.

a few days ago users started complaining because sometimes they would
get a message like:

------------------------------------------
The requested URL could not be retrieved
  
While trying to retrieve the URL: http://mail.yahoo.com/

The following error was encountered:

     Unable to determine IP address from host name for
     mail.yahoo.com                                   
     
The dnsserver returned:

     No Address records
     
This means that:
 
 The cache was not able to resolve the hostname presented in the URL.
 Check if the address is correct.                          
------------------------------------------

poking in the DNS, i find:

Name:    login.yahoo.akadns.net
Addresses:  64.58.76.98, 64.58.76.99
Aliases:  mail.yahoo.com, login.yahoo.com

so, mail.yahoo.com isn't an A record, but a CNAME pointing to something
at akadns.

we are thinking there might be some issue with some dynamic nature of yahoo's
dns.

are we barking up the right tree?
