DNS Monitoring Service (DNSMON)
The RIPE NCC's DNS Monitoring Service (DNSMON) is an active measurement service that provides a comprehensive, objective and up-to-date overview of the quality of the service offered by high-level Domain Name System (DNS) servers. It uses our RIPE Atlas network to provide an up-to-date service overview of certain DNS root and top-level domain (TLD) name servers. An important feature is the ability to view historical data, which allows for quick analysis of both past and present DNS issues.

K-root
The RIPE NCC operates K-root, one of the 13 Internet root name servers. The K-root service is provided by a set of distributed nodes using IPv4 and IPv6 anycast.

Reverse DNS Zonecheck
This tool can be used to check a reverse zone setup in the DNS. It follows the routines that the RIPE NCC uses for reverse zone delegation.

AS112
The RIPE NCC is one of many operators participating in the AS112 Project, which aims to provide a clean, well-lit destination for DNS queries concerning RFC1918 and other DSUA networks.

DNS Lameness
The RIPE NCC do not run DNS Lameness checks on servers listed as delegation points within the RIPE NCC delegated zones.
