What's Your (IP) Address Worth?

Now that we're officially out of IPv4 addresses, a new marketplace has sprung up to buy and sell them (or rather, to broker transfers from one organization to another with dollar figures attached). Sites like www.depository.net, www.addrex.net and www.tradeipv4.com look like they'll be with us for a while.
Having said that, ARIN.NET continues to administer all transfers in North America (US, Canada and parts of the Caribbean), including transfers of addresses that were allocated by Internic, back before ARIN.NET existed (https://www.arin.net/about_us/media/releases/20110330.html). This is a good thing, since most ISPs won't route for an address block unless the registration is correct at the appropriate RIR (Regional Internet Registry ==> https://www.arin.net/knowledge/rirs.html)
I can't personally vouch for any of these sites. As always, evaluate the reputation of sites you do business on, and this certainly counts as business transactions! It's also important to run any transfer of address space through the RIR that has authority in your jurisdiction. You don't want to find that the addresses you thought you had are not in fact yours!
