    I don't think I've seen a banner ad in a year or so.

    I used IE the other day for the first time in ages, and was surprised by a popup.

    Seriously, Slashdot needs to shape up, or stop trying to be a news site. This happened yesterday. If you can't get your editors to greenlight stories faster than 24hours in advance, let subscribers do it like Fark does.

      Some alternatives that are fun:

      1. Install privoxy from sourceforge.net. This is a local http proxy that allows you to filter out web content using regular expressions. So you can easily blank out any URL that contains the string "doubleclick." This is easier and more complete than trying to enumerate all the hostnames that Doubleclick Inc. uses. Privoxy is multi-platform; you can use it under Linux, Windows, etc.

      2. Install posadis from sourceforge.net. This is a caching DNS server that you can install on your computer. It allows you to control how domain names (like *.doubleclick.net) get resolved by ALL the programs on your computer. I use it to essentially blackhole domains that I don't like. Once again, this is a multi-platform project. In particular, under Windoze, it runs as a service. It has an irritating bug: under Windoze, it will occasionally start using 100% CPU. When this happens, you have to restart the posadis service. A hassle, verily. But I enjoy having the control that derives from running my own DNS server.

      3. Use a firewall (hardware or software) to block out numeric IP addresses. For example, 216.73.92.112 is www.doubleclick.net, so it should be blocked. I used to use this approach. I liked the idea of absolutely blocking any packets going to or from the bad guys, regardless of the DNS name used. The problem with this approach is that outfits like doubleclick.net will use a ton of different numeric IP addresses, and it's difficult to keep up with them.

      I should mention there's a firefox extension that blocks ads based on regular expressions. Yet another reason to drop IE.

    Not that box, I am pinging their primary DNS server and still getting a reply, they have 4.

    ns1.doubleclick.net
    ns2.doubleclick.net
    ns3.doubleclick.net
    ns4.doubleclick.net

    This way you can check your networks to see if any machines are hitting these DNS server. I am going to keep my ping going to make sure ns1 stays online. j/k

    You can do your part to reduce the load by adding doubleclicks ad-servers to your /etc/hosts file as 127.0.0.1 (this can be done in windows too).

    Have you tried firefox?

    I have it installed on this box, along with IE. I still use IE half the time. I use mozilla on my linux boxes, but (i hate to say it) there are are certain aspects of IE that are more comfortable, or at least more familiar. Keep in mind, im an old geek, not a hobbiest. Been using Linux and GNU software for years and it is catching up very fast, but I still use the tools that make me more productive, and IE fits that bill at least half the time. The pops ups don't annoy me as bad as they used to, now that they are all blank pages.

    Oh, i found that hosts file address here. I chang a few lines for my uses (travelocity.com and osdn.com for instance) because it may break a few things, like Pogo, but its a great template for a hosts file if you customize it a bit for yourself.
