Knot DNS supports DNSSEC signing and among others hosts root zone (B, K, and L root name servers ), several top-level domains .
Some OpenNIC recursive servers (Tier 2 servers) are known for their high speeds and low latency, relative to other more widely used DNS recursors, [4] as well as their anonymizing or no-logging policies. [5] [6] Many servers offer DNSCrypt. Community volunteers operate Tier 2 servers across a multitude of geographic locations.
Round-robin DNS is a technique of load distribution, load balancing, or fault-tolerance provisioning multiple, redundant Internet Protocol service hosts, e.g., Web server, FTP servers, by managing the Domain Name System's (DNS) responses to address requests from client computers according to an appropriate statistical model.

A managed DNS provider offers either a web-based control panel or downloadable software that allows users to manage their DNS traffic via specified protocols such as: DNS failover , dynamic IP addresses , SMTP authentication , and GeoDNS .
dnsmasq caches DNS records, reducing the load on upstream nameservers and improving performance, and can be configured to automatically pick up the addresses of its upstream servers. dnsmasq accepts DNS queries and either answers them from a small, local cache or forwards them to a real, recursive DNS server.

DNS hosting service is optimal when the provider has multiple servers in various geographic locations that provide resilience and minimize latency for clients around the world. By operating DNS nodes closer to end users, DNS queries travel a much shorter distance, resulting in faster Web address resolution speed.
