Bot Blocking in IPV6
what's your strategy?

 6:08 pm on Feb 3, 2011 (gmt 0)

Thought I'd bring up a topic we keep hearing about but for some reason nobody is really discussing, IPV6, which is definitely the elephant in the room.

What is everyone planning to do when the internet transitions to IPV6 as expected by 2012?

There will be so many IP blocks out there that blocking them using traditional IP blacklisting methods in Apache or the standard server firewall will bring performance to a screeching halt.

How will IPV6 impact your current IPV4 lists of IPs?

Anyone have any experience and/or developed a strategy for blocking bots in IPV6 they'd like to share?

Hey Bill,
Some where there's an old explanation on Webmaster World on how to block the IPV6 ranges.

Don't recall if it was this forum or one of the others.
Nor do I recall who provided the explanation

Well I definately started thinking about this a few month ago. We currently get the IPV4 Data from a paid source and I also have an old script of mine that parces the data available(havent run the routine in a while) from the ARIN, RIPE etc ftp sites.

I think I will still go the route of the way we have it now, the IP data is in DB and then ....

It's on a back burner at this point.

I use MySQL to hold the blocklist. IPV6 will certainly increase the serving time of matches but I suppose I'll have to wait and see by how much.

Or I could just retire. The internet is rapidly going to hell on a handcart - actually, more like on a Formula 1 racer! :(

How imminent a problem is this? I hope we have a few more years or so before we have to seriously worry about this.

I would think it depends on how much of a tech geek you are, and what type of environment you work in.

As for myself, I'm actively pursuing the issue inhouse currently. mail servers, website, user seats, etc.

Almost all the IPV4 ranges have now been allocated - there was a major allocation bout last year, mostly to US companies. It now depends, I suppose, on how many of those IPs get used up and how fast. With some companies allocating /15 and more to clouds, it could be soon. :(
