IP Address Distribution Doesn’t Fit in the Registry/Registrar Model

At the IGF2010 in Vilnius, two folk are floating a trial balloon about separating the allocation function from the registry services function. Currently, these functions are seen as indivisible by the Internet addressing community. In other words, one gets an allocation or assignment from a RIR and the RIR adds the assignment to their database... The question being asked is "Is it time for a split between allocation and services for Internet number resources as was the case for domain name resources?" My answer is no

Suggestions on IDN Variant Management

To some applicants, ICANN's variant management policy in DAG4 has become a big obstacle to the new generic Top-Level Domain (gTLD) application. The policy is to delegate the string while reserving the variants, and these variants will not be delegated until a sound mechanism is developed and the desired variants are evaluated. But for some languages, Chinese for example, the so called string and its variant, namely simplified Chinese and traditional Chinese, are equivalent and must be simultaneously delegated.

DNS Clients Do Request DNSSEC Today

After the DNS root zone was finally signed and a number of Top-Level Domains (TLDs) began signing their zones, we were curious to see how many clients actually request DNSSEC information. We looked at the RIPE NCC server that provides secondary service to several country code top-level domains (ccTLDs).

Ensuring Maximum Resilience to the DNS?

Yesterday CommunityDNS noticed a sudden, heavy spike in traffic through its Anycast node in Hong Kong. While comfortably processing queries at 863,000 queries per second for close to 2 hours the occurrence was undeniable. While we can't say the increase in traffic was specifically due to DDoS, its sudden increase is suspicious and reminds us that DDoS is still a popular tool used by the malicious community.

The Window of Opportunity for ccTLDs

The announcement that .co has already achieved over 450,000 new registrations since the opening up of the second level a month ago demonstrates that there is strong demand in the global domain name marketplace for quality new domain spaces. Though .co is the country code Top Level Domain (ccTLD) for Colombia, the second-level registrations (i.e. company.co) are available on a global basis and it is being pitched as a direct competitor to the dominant .com gTLD. Google has altered its algorithm to increase the relevance of search results in the .co domain by treating .co as a gTLD...

IT Risks for Cloud Computing

As the industry-wide paradigm shift to cloud computing and software-as-a-service gradually continues to make the transition from buzz to reality, security and availability continue to emerge as the main barriers to customer adoption. A recent ISACA survey of over 1,800 US IT professionals found that only 17 percent believe the benefits of cloud computing outweigh the risks. Only one in 10 respondents said they would consider using software-as-a-service (SaaS) for mission-critical applications.

The Web is Dead: What This Means to ICANN, New gTLD Program and the Domain Industry

While we are spending years figuring out how to create the perfect generic Top-Level Domain (gTLD) launch and guidebook, the Internet is moving along at an extraordinary pace without any care about ICANN policy-making. The fact of the matter is ICANN is a ghost to the ordinary person or Internet company. You can not imagine how many times I had to explain what ICANN is, what ICANN does and why ICANN is important.

ccIDNs: So Many Choices, So Little Time

As a result of ICANN's IDN ccTLD Fast Track process, which was launched in November of last year, a number of new ccIDNs (Country Code Internationalized Domain Names) have been successfully added to the root including: China (.??, .??), Egypt (.???), Hong Kong (.?? ), Russia (.??), Saudi Arabia (.????????), Taiwan (.??, .??) and the UAE (.??????). ... With so many new registration possibilities available, and several Sunrise periods quickly approaching, many corporate domain managers are asking themselves whether new registrations should be added to portfolios which are already bursting at the seams.

An Attack on DNS is an Attack on the Internet

On Saturday Aug 7th, DNS provider DNS Made Easy was the target of a very large denial of service attack. As far as can be determined the total traffic volume exceeded 40 Gigabit/second, enough to saturate 1 million dialup Internet lines. Several of DNS Made Easy's upstream providers had saturated backbone links themselves. There are indications that not only DNS Made Easy suffered from this attack, but the Internet as a whole.

Putting String Similarity into Context: Bulgaria’s IDN (.??) vs. Brazil’s ccTLD (.br)

Bulgaria is a nation which is directly impacted by the current Fast Track automatic disqualification when Top-Level Domain (TLD) strings are "confusingly similar" to other TLDs, in this case an Internationalized Domain Name (IDN) country code Top-Level Domain (ccTLD). Bulgaria has already been declined twice (in late 2009, and in May of 2010) to register the *.?? Cyrillic IDN on the premise that it looks confusingly similar to Brazil's *.br ASCII TLD. Being a native Bulgarian, I did not see how these two strings are similar
