Architelos: shadiest new gTLD is only 10% shady
Disputing the recent Blue Coat report into “shady” new gTLDs, domain security firm Architelos says that the shadiest namespace is just under 10% shady.
That’s a far cry from Blue Coat’s claim earlier this week that nine new gTLDs are 95% to 100% abusive.
Architelos shared with DI a few data points from its NameSentry service today.
NameSentry uses a metric the company calls NQI, for Namespace Quality Index, to rank TLDs by their abuse levels. NQI is basically a normalized count of abusive domains per million registered names.
According to Architelos CEO Alexa Raad, the new gTLD with the highest NQI at the end of June was .work.
Today’s NameSentry data shows that .work has a tad under 6,900 abusive domains — almost all domains found in spam, garnished with just one suspected malware site — which works out to just under 10% of the total number of domains in its zone file.
That number is pretty high — one in 10 is not a figure you want haunting your registry — but it’s a far cry from the 98.2% that Blue Coat published earlier this week.
Looking at the numbers for .science, which has over 324,000 names in its zone and 15,671 dodgy domains in NameSentry, you get a shadiness factor of 4.8%. Again, that’s a light year away from the 99.35% number published by Blue Coat.
Raad also shared data showing that hundreds of .work and .science domains are delisted from abuse feeds every day, suggesting that the registries are engaged in long games of whack-a-mole with spammers.
Blue Coat based its numbers on a sampling of 75 million attempted domain visits by its customers — whether or not they were valid domains.
Architelos, on the other hand, takes raw data feeds from numerous sources (such as SpamHaus and SURBL) and validates that the domains do actually appear in the TLD’s zone. There’s no requirement for the domain to have been visited by a customer.
In my view, that makes the NameSentry numbers a more realistic measurement of how dirty some of these new gTLDs are.
