[AusNOG] Anyone else notice the click frenzy traffic

[Seamus Ryan]

Hit send a little early:

No, this is quite the norm, particularly with sites that are offloaded to a CDN provider.

Example:

Qantas offloading to Akamai:

root at srv1-au [~]# host -t a qantas.com.au qantas.com.au has address 204.74.99.100

root at srv1-au [~]# host -t a www.qantas.com.au www.qantas.com.au is an alias for www.qantas.com.au.edgekey.net.
www.qantas.com.au.edgekey.net is an alias for e1629.b.akamaiedge.net.
e1629.b.akamaiedge.net has address 118.214.198.197

Ebay:

root at srv1-au [~]# host -t a ebay.com.au
ebay.com.au has address 66.135.215.61
ebay.com.au has address 66.135.200.23

root at srv1-au [~]# host -t a www.ebay.com.au
www.ebay.com.au is an alias for au.ebay.com.edgesuite.net.
au.ebay.com.edgesuite.net is an alias for a1465.g.akamai.net.
a1465.g.akamai.net has address 150.101.195.97
a1465.g.akamai.net has address 150.101.195.98

People just redirect to www to force users via a CDN. In this case clickfrenzy appears to be using Edgecast.

On this topic, I thought it was still down for me, then I realised that the A record for clickfrenzy.com.au doesn't match the A record for www.clickfrenzy.com.au! Does this practise frustrate anyone else? 
(Especially since I hate to type www. in front of things).
