What is a name collision?
According to ICANN, "a name collision occurs when an attempt to resolve a name used in a private name space (e.g. under a non-delegated Top-Level Domain, or a short, unqualified name) results in a query to the public Domain Name System (DNS). When the administrative boundaries of private and public namespaces overlap, name resolution may yield unintended or harmful results.
Name collisions are not new. The introduction of any new domain name into the DNS, whether a generic TLD, country code TLD or second-level domain name, creates the potential for name collision. However, queries for un-delegated TLDs at the root level of the DNS have received renewed attention because certain applied-for new TLD strings could be identical to name labels used in private networks. A secure, stable and resilient Internet is ICANN's number one priority. Therefore, we've made a commitment to the Internet community to launch a substantial effort to mitigate and manage name collision occurrence."
You may have noticed that many of the new TLD Registries have recently been releasing their domain name collisions. This is being done after working with ICANN to deal with any potential issues that could arise from these domain names.
