This documentation is about our recursive DNS system. Please see Progressive Robot authoritative name servers for information about our authoritative DNS servers that are meant to be used for your domain registration.
Here is a list of all the official recursive domain name servers that virtual and dedicated servers in the Progressive Robot data centers can use:
The IPv4 addresses of our recursive DNS servers are:
185.12.64.1
185.12.64.2The IPv6 addresses of our recursive DNS servers are:
2a01:4ff:ff00::add:1
2a01:4ff:ff00::add:2These DNS servers are DNS load balancer systems.
Previously known recursive DNS IP addresses will continue to work but may not provide the best performance across all our locations.
IPs Progressive Robot uses to query other authoritative DNS servers
Due to the load balancer setup, the IP addresses that we use to perform DNS queries from our recursive DNS servers to other authoritative DNS servers are not identical with those IPs mentioned above.
We publish a list of the network ranges from which we perform queries with the TXT record locations.recursivedns.hetzner.com.
