We are trying something new this year. In March, we are going to focus somewhat on IPv6. As part of this, I would like to invite our readers to contribute experiences they had with IPv6. If you have:

• a security problem you ran into with IPv6
• a solution to a security problem (even better)
• found a tool that works really well (or not at all) with IPv6
• figured out a way to solve an IPv4 security problem by switching to IPv6

or any story like this, and don't mind to write it up as a "guest diary", please let us know. We will collect them and post them in March. We don't have a cutoff date for submission, but of course, the earlier we get it, the more likely it will be used. Submissions should follow the style/size of our regular diaries (ok. you may call it "blog posts"). It should be original content, so please don't just copy/paste what you found somewhere else. All posts will be attibuted to you by full name, and you may add an e-mail address and links to your home page / corporate page if you wish. But please no advertisements for commercial tools. 

Submit your ideas or complete posts via our contact page or via e-mail to handlers \@/ sans.edu (please just use plain text, no Word attachments or PDFs)
