[ 8 ] This does not mean that there are only 13 physical servers; each operator uses redundant computer equipment to provide reliable service even if failure of hardware or software occurs.
OpenDNS offers DNS resolution as an alternative to using Internet service providers' DNS servers or locally installed DNS servers. OpenDNS has adopted and supports the DNSCurve secure protocol. [2] OpenDNS provides the following recursive nameserver addresses [3] for public use, mapped to the nearest operational server location by anycast routing.
The 1.1.1.1 DNS service operates recursive name servers for public use at the twelve IP addresses listed below. [11] These addresses are mapped to the nearest operational server by anycast routing.
