Yes! This is the one, the only, the original "Ad hoc IPTools Page." There are many imitators out there (and for all you "hackers" who have stolen my HTML code without my permission—pox on you!), but none are as up-to-date and useful as this very page right here.

     Please notify Rich Tatum if these links break or if you discover a tool which ought to be included here. From time to time one or more of these tools will be unavailable due to various reasons: network traffic, server downtime, loss of support for the tools listed, or the random vagaries of the Web. For that reason, many of these tools are redundant—if one tool doesn't work, try using another. Please let me know and I'll put the changes on my list of things to do. (I'm not the creator of any of these tools—I'm not that bright!)

     These tools are unsupported. Contact the tool's source if you have problems with a specific tool. But do feel free to let me know when a form needs updating.
