Ok,

I won't claim DNS guru'ness but this just seems quite crazy to me... Is 
anyone else seeing this, does it make sense and if so why.

Everything in me is screaming, this is just stupid... hopefully I'm right.


[hhoffman at localhost]# host download.windowsupdate.com
download.windowsupdate.com is an alias for download.windowsupdate.nsatc.net.
download.windowsupdate.nsatc.net is an alias for 
download.windowsupdate.com.fp.nsatc.net.
download.windowsupdate.com.fp.nsatc.net is an alias for 
download.windowsupdate.com.c.footprint.net.
download.windowsupdate.com.c.footprint.net has address 209.245.20.93
download.windowsupdate.com.c.footprint.net has address 63.236.48.222
download.windowsupdate.com.c.footprint.net has address 208.172.128.253
download.windowsupdate.com.c.footprint.net has address 208.172.64.254
download.windowsupdate.com.c.footprint.net has address 67.72.8.94


so, this is a alias->alias->alias->several A records?


Thanks,
Harry
