For the past 27 years, I have owned a class C or /16 block of IPv4 addresses. I don’t recall what prompted me back then to apply for my block: I didn’t really have any way to run a network online, and the Internet was just catching on at the time. The transaction took moments with the exchange of a couple of emails, and there was no cost to obtain the block. 

Earlier this year I was reminded that I still owned this block and that I could sell it and make some quick cash. What was interesting is that in all the years I had the block I had never really used it for anything. I had never set up any computers using any of the 256 IP addresses associated with it. In used car terms, it was in mint condition. Virgin cyberspace territory. So began my journey into the used marketplace that began just before the start of the new year. I document some of this journey in a blog post for Network Solutions. I tell the story about what I learned and what I would do differently knowing what I know now. You can see that block transfers have become a thing from this graph.

I also wrote an eBook for them based on this experience if you want to learn more about the address block aftermarket. And in this more personal post,Beware that it isn’t easy or quick money by any means. It will take a lot of work and a lot of your time.
