Addressing DNS abuse and maintaining a healthy DNS ecosystem are important components of Verisign’s commitment to being a responsible steward of the internet. We continuously engage with the Internet Corporation for Assigned Names and Numbers (ICANN) and other industry partners to help ensure the secure, stable and resilient operation of the DNS.
Today, we released the latest issue of the Domain Name Industry Brief, which shows that the first quarter of 2021 closed with 363.5 million domain name registrations across all top-level domains (TLDs), a decrease of 2.8 million domain name registrations, or 0.8%, compared to the fourth quarter of 2020.1,2 Domain name registrations have decreased by 3.3 million, or 0.9%, year over year.1,2
At Verisign we have a commitment to making a positive and lasting impact on the global internet community, and on the communities in which we live and work.
A name collision occurs when a user attempts to resolve a domain in one namespace, but it unexpectedly resolves in a different namespace. Name collision issues in the public global Domain Name System (DNS) cause billions of unnecessary and potentially unsafe DNS queries every day. A targeted outreach program that Verisign started in March 2020 has remediated one billion queries per day to the A and J root name servers, via 46 collision strings. After contacting several national internet service providers (ISPs), the outreach effort grew to include large search engines, social media companies, networking equipment manufacturers, national CERTs, security trust groups, commercial DNS providers, and financial institutions.
