The DNSRF have been creating League Tables which rank domain name registrars, top-level domain (TLD) providers and Autonomous System Numbers (ASNs) based on their relative levels of online abuse reports. The TLD League Tables have been publicly available on the DNSRF website since 2023, the Registrar League Tables were launched in January 2025 and, this quarter, the ASN League Tables were released.

The aim of the League Tables is to encourage TLDs, registrars and ASNs to increase their mitigation rates as well as implement stronger policies on internet abuse. In doing so, DNSRF hopes to minimise the financial and emotional distress inflicted on the victims of scams and fraud. The League Tables can also assist businesses, individuals and policy makers in making informed decisions about domain registrations, as well as raising awareness around DNS abuse.  

This report aims to explain the recent improvements and changes made to methodology of the League Tables and give an overview of some of the recent trends observed in the DNS landscape.
