iptables and ads

[woksy]

Hi people ! ;-)
I was just answering myself if i could stop ads loading from web pages such as 
yahoo, lycos, & co ? (i don't mean blocking popup, just stopping those boring 
ads from loading)
I tried to do this with something like that:
$IPTABLES -A INPUT -i $EXTIF -s 216.73.92.112/32 -j drop-and-log-it
but it seems that I mistaked.
Can anybody help me please ? 
Thanks

Hello,

I would solve this like this way

iptables  -N  drop-and-log-it
iptables -A input -i $EXTIF -j drop-and-log-it
iptables -A drop-and-log-it  -s 216.73.92.112/32 -j DROP
iptables -A drop-and-log-it  -s 216.73.92.112/32 -j LOG --log-prefix 
"SOMETHING_TEXT: "

It isn't elegant, but it might work

I think when you enter any application domain you'll better be off with
some solution at that (application) level. Use a transparant proxy and
block the communication there.

Well, the line above by itself is  not incorrect but:

0) what doesn't work?
1) what does drop-and-log-it do.
2) why do you kill the communication in INPUT? Not in OUTPUT?
3) Most of the ad stuff have a big DNS pool for the servers. I don't
   think your /32 catches them all.
