An IPv4 Windfall: Circuit City’s Addresses Now On The Block, Along With Borders

Written by Evan Schuman

Following last week’s word that the Borders bankruptcy was unleashing tens of thousands of much-needed IPv4 addresses back into the retail online world comes word that fellow bankrupt retailer Circuit City is now selling its old IPv4 addresses—and Circuit City has twice as many as Borders. That will put almost 197,000 of the hard-to-get addresses out there for the highest bidder.

Let’s take this slowly. Circuit City hasn’t been an in-store national chain since 2009. But when it liquidated, no one apparently thought about the IP addresses, according to Gabe Fried, the founding principal of Stream Bank LLC, which handled Circuit City’s liquidation and is now handling the one for Borders.

“The people who knew that [Circuit City] had these assets left the company” rather abruptly when Circuit City didn’t find a buyer for the chain and liquidation proceedings began, Fried said. “The problem involved management bandwidth and a lack of knowledge of [the IPv4 addresses’] existence.”

The IPv4 addresses from Borders are a /16 contiguous Class B block, and “we have two additional Class B blocks from Circuit City,” Fried said.

How much are these numeric treasures likely to cost? Fried said he hopes to pull in about $11 an address, which is roughly how much Nortel’s IPv4 addresses sold for. Back in March, Microsoft picked up about 666,000 of the Nortel addresses for $7.5 million.

But will the ultimate price be a lot more? “We anticipate that the demand will exceed supply,” Fried said.

Among other intellectual property goodies up for sale from Borders is one abandoned Patent application involving virtual bookshelves. The application was abandoned by Borders after the Patent office indicated it was not inclined to approve the patent given a lack of novelty, Fried said, so it’s not likely to be a hot-seller.

But there are some leftover Circuit City patents involving digital media that Fried said looked much more compelling.

Borders is also selling a lot of private customer data, as expected. Documents with the bankruptcy proceedings describe it as “a proprietary database of customer information tracked by customer E-mail address and including customer data captured at the point of sale on and through the Borders Rewards [approximately 21 million active members] and Borders Rewards Plus [approximately 1.8 million active members] programs. Customer data is maintained by Borders with the assistance of a third-party service provider, Epsilon Data Management. Borders regularly evaluates its customer data using RFM (recency, frequency and monetary) analysis techniques.”

Given how quickly E-mail addresses change, Fried was asked how perishable he considered the almost 23-million-name database. He said that E-mail databases have recently been getting out-of-date more slowly, as layoff-worried employees stop using their corporate domain E-mails (as in and instead use personal addresses (as in for lists such as Borders.

Another popular asset is and several variations of that domain. It’s not clear what will sell for, but Circuit City’s Internet assets sold for about $17 million and Borders’ Internet assets are expected to sell in that same range, perhaps a little lower.

The bid deadline is September 8, with an auction date of September 14.

Why Did Gonzales Hackers Like European Cards So Much Better?

I am still unclear about the core point here-- why higher value of European cards. Supply and demand, yes, makes sense. But the fact that the cards were chip and pin (EMV) should make them less valuable because that demonstrably reduces the ability to use them fraudulently. Did the author mean that the chip and pin cards could be used in a country where EMV is not implemented--the US--and this mis-match make it easier to us them since the issuing banks may not have as robust anti-fraud controls as non-EMV banks because they assumed EMV would do the fraud prevention for them Read more...
Two possible reasons that I can think of and have seen in the past - 1) Cards issued by European banks when used online cross border don't usually support AVS checks. So, when a European card is used with a billing address that's in the US, an ecom merchant wouldn't necessarily know that the shipping zip code doesn't match the billing code. 2) Also, in offline chip countries the card determines whether or not a transaction is approved, not the issuer. In my experience, European issuers haven't developed the same checks on authorization requests as US issuers. So, these cards might be more valuable because they are more likely to get approved.

A smart card slot in terminals doesn't mean there is a reader or that the reader is activated. Then, activated reader or not, the U.S. processors don't have apps certified or ready to load into those terminals to accept and process smart card transactions just yet. Don't get your card(t) before the terminal (horse). Read more...
The marketplace does speak. More fraud capacity translates to higher value for the stolen data. Because nearly 100% of all US transactions are authorized online in real time, we have less fraud regardless of whether the card is Magstripe only or chip and PIn. Hence, $10 prices for US cards vs $25 for the European counterparts. Read more...
@David True. The European cards have both an EMV chip AND a mag stripe. Europeans may generally use the chip for their transactions, but the insecure stripe remains vulnerable to skimming, whether it be from a false front on an ATM or a dishonest waiter with a handheld skimmer. If their stripe is skimmed, the track data can still be cloned and used fraudulently in the United States. If European banks only detect fraud from 9-5 GMT, that might explain why American criminals prefer them over American bank issued cards, who have fraud detection in place 24x7. Read more...
