On Windows, I do ipconfig /displaydns
One record is:
na4.salesforce.com
----------------------------------------
Record Name . . . . . : na4.salesforce.com
Record Type . . . . . : 5
Time To Live . . . . : 8
Data Length . . . . . : 8

CNAME Record . . . . : na4-was.salesforce.com
I see no IP for it.
How does Windows resolve the IP for this then?
Note: there is no other entry for na-4-was.salesforce.com.
1So it never caches it? And has to resolve it each time? – dublintech – 2012-06-17T10:13:32.730
Apparently not. Bizarrely tracert-ing na4-was results in it showing up as a cname for itself... which makes no sense at all. – Journeyman Geek – 2012-06-17T10:17:31.407
@dublintech, sorry, why do you think cname records aren't cached? They are cached like anything else. – Zoredache – 2012-06-17T10:28:26.847
@Zoredache there was no corrresponding entry for the cname record in the cache, in this case. – dublintech – 2012-06-17T20:16:30.870
