Sorry I forgot to add that.On more trial and error - I see

1> on https no ad is displayed

2> Even on ftp sites no ad is displayed.

Only happens with pages on http://.

Another interesting thing, after installing adblock-plus, an x mark is 
displayed on http pages just where the ad used to be.After 
right-cliking, i see an url 172.16.2.194/streamride/* in adblock plus 
filter blocking dialog.Interestingly my ISP is also running squid 
3.2.0.4 on streamride host which is evident by trying to connect to 
random ip addresses and seeing the error page.
