The Sony PlayStation Network and Qriocity service have been down since Wednesday the 20th. Sony is still working on bringing them back online. Sony is communicating regularly on this - you can find their original and current updates here:

and

Reading between the lines, they seem to be following the methodology for Incident Response, commonly phrased in these steps that I learned in SEC504: 

  • Preparation
  • Identification
  • Containment
  • Eradication
  • Recovery
  • Lessons Learned

Given that we're a number of days in, I hope that they are working on later phases of Eradication, making sure that the original attack vector is taken care of so that once they bring the service back online they won't see a recurrance of the event.

Hats off to them - they're doing all the right things, and communicating regularly with their client community as they do it ! I feel for them, given the length of the outage though.

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!
