Re: [Other] Insight is Injecting Pop Up Ads into customer web se

I'm not an Insight customer, did the nslookup for b.casalemedia.com and it resolved to 64.213.163.83. Not an Insight owned IP.

Have a look for yourself:

»whois.domaintools.com/64.213.163.83

Insight is not generating this activity. Probably the sites you're surfing to that are dropping pop-unders.

Do you guys not understand what I'm saying here?

Insight Communications (cable ISP) is wanting to inject popups into HTTP data. So what they do is install these Akamai devices to serve out the HTML popup ads. They make a change in their DNS servers so that b.casalemedia.com resolves to this server which lives in their datacenter. Of course it has to be THEIR ip address. Look at my nslookups in the picture attached to the first message. This was an nslookup on Insight Communication's DNS server. So that means THEIR DNS server is answering requests for b.casalemedia.com and resolving it to 74.128.17.201 and 74.17.203. So now the ad doesn't look like its going to insight. They do this to mask where the ad is coming from.

I'm getting these DNS servers via DHCP of course. My primary DNS server is 74.128.17.114 and my secondary DNS server is 74.128.19.102.

Here are the results of nslookups to each DNS server:
******************
C:\nslookup b.casalemedia.com 74.128.17.114
Server: cache1.insightbb.com
Address: 74.128.17.114

Non-authoritative answer:
Name: a1083.g.akamai.net
Addresses: 74.128.17.203
74.128.17.201
Aliases: b.casalemedia.com
b.casalemedia.com.edgesuite.net
**********************
C:\nslookup b.casalemedia.com 74.128.19.102
Server: cache2.insightbb.com
Address: 74.128.19.102

Non-authoritative answer:
Name: a1083.g.akamai.net
Addresses: 74.128.17.203
74.128.17.201
Aliases: b.casalemedia.com
b.casalemedia.com.edgesuite.net
***********************

Of course your DNS servers are not going to resolve an Insight address to this hostname. This is a change that Insight has made in THEIR DNS servers.

When you click on the pop up ad itself you go to:

»c.casalemedia.com/c/1/1/67739/aH···Y3QvMDEv

c.casalemedia.com also resolves to an Insight Communications address:

************************
C:\nslookup c.casalemedia.com
Server: cache1.insightbb.com
Address: 74.128.17.114

Non-authoritative answer:
Name: a1195.g.akamai.net
Addresses: 74.128.17.241
74.128.17.211
Aliases: c.casalemedia.com
c.casalemedia.com.edgesuite.net
*************************

So the solution here is to either add a entry into your hosts file to point b.casalemedia.com and c.casalemedia.com to 127.0.0.1 so you will not see the data or you can use recursive DNS servers that do not belong to Insight. Either one will block these pop ups from your system.

Yawn -- Do you not understand what everyone else is saying? No one else is seeing this problem. I use Insight continuously in the Louisville area and have never seen the problem you claim -- although I can't say that I would care if it did happen.

casalemedia is nothing but a popup ad service used my numerous websites, so if Insight were substituting their choice of stupid popup ad instead of the website's choice of stupid popup ad, I don't see that as a problem for the consumer (although I can see where casalemedia might care).
