Bank takes blame for gTLD name collision

The Commonwealth Bank of Australia, which has applied for the new gTLD .cba, has told ICANN that its own systems are to blame for most of the error traffic the string sees at the DNS root.

The company wants ICANN to downgrade its gTLD application to “low risk” from its current delay-laden “uncalculated” status, saying that it can remediate the problem itself.

Since the publication of Interisle Consulting’s name collisions report, CBA said it has discovered that its own systems “make extensive use of ‘.cba’ as a strictly internal domain.”

Leakage is the reason Interisle’s analysis of root error traffic saw so many occurrences of .cba, the bank claims:

As the cause of the name collision is primarily from CBA internal systems and associated certificate use, it is within the CBA realm of control to detect and remediate said systems and internal certificate use.

One has to wonder how CBA can be so confident based merely on an “internal investigation”, apparently without access to the same extensive and highly restricted data set Interisle used.

There are many uses of the string CBA and there can be no guarantees that CBA is the only organization spewing internal DNS queries out onto the internet.

CBA’s comment is however notable for being an example of a bank that is so unconcerned about the potential risks of name collision that it’s happy to let ICANN delegate its dot-brand without additional review.

This will surely help those who are skeptical about Interisle’s report and ICANN’s response to it.

  1. Kevin, like the CBA, TLD Registry Ltd views the risks of collisions to be low, and as Antony Van Couvering and others have said, the ease of mitigation very straightforward. As a new gTLD registry of primarily Chinese strings (with zero recorded collisions), the recommendations of the “Addressing the Consequences of Name Collisions” report pose a troubling impact on the New gTLD program — both business and, in China, reputational. Our CEO blogged on this subject, with before-and-after scenarios of the report’s impact, at http://internetregistry.info/name-collisions-delays-unnecessary-for-most-new-gtld-registries/
