$ host www.microchip.com
www.microchip.com                                      CNAME cnwww.microchip.com.edgekey.net
cnwww.microchip.com.edgekey.net                        CNAME cnwww.microchip.com.edgekey.net.globalredir.akadns.net
cnwww.microchip.com.edgekey.net.globalredir.akadns.net CNAME e1721.a.akamaiedge.net
e1721.a.akamaiedge.net                                 A
