Comment(by nerddtvg):

 I see what scurrilous saw with the DNS strings, however my Yahoo client
 doesn't lookup these hosts. It instead does the following:

 Lookup A record for vcs1.msg.yahoo.com (68.180.216.31)

 Sends HTTP request to IP:
 GET /capacity HTTP/1.1
 Cache-Control: no-cache
 Host: vcs1.msg.yahoo.com
 User-Agent: Mozilla/5.0
 Connection: Close

 Response:
 HTTP/1.1 200 OK
 Content-Length: 46
 Content-Type: text/plain; charset=utf-8
 Cache-Control: max-age=0, must-revalidate
 Expires: Sun, 10 Jun 2007 12:01:01 GMT
 COLO_CAPACITY=1
 CS_IP_ADDRESS=68.180.217.30

 Then it connects to 68.180.217.30:5050 for paging. The rDNS comes back as
 cs125.msg.sp1.yahoo.com. which seems to follow a similar pattern as the
 lookups Pidgin does.

 I'm not an expert in the protocols here, so I'm just guessing. I compared
 with Pidgin does with the IP it looks up for the paging server and saw the
 same results as with the connections Yahoo made. It seems that Yahoo has
 changed their protocols a bit. Hope this helps.
