Australian DNS resolver

Location: Sydney, Australia

Features

Privacy Focused
No Censorship
No Logging (aggregate statistics like latency are gathered using munin, see server statistics)
DNSSEC validation
Build on open source technologies
DNS Rebind protection. See the config for the currently filtered IPs. As a consequence spam block lists (RBL) such as spamhaus.org will no longer work. Also note your public IP might still be vulnerable. [1] [2] [3] [4] [4 slides]
OpenNIC TLDs
Qname minimisation (RFC 7816)
Query pre-fetching using Unbound's algorithm
Available over the DNSCrypt protocol
Supports DNS-over-HTTPS (DoH) (RFC 8484) which is basically DNS over HTTP/2
Supports DNS-over-TLS (DoT) (RFC 7858)

The server configuration is freely available on github:

https://github.com/publicarray/dns-resolver-infra

If there are any problems please open an issue or send me a DM.

Notes:

No logging means that I don't log dns queries but certain statistics

such as the latency and query status are logged see

https://dns.seby.io/stats.html for pretty graphs

While the resolver is freely available abuse will not be tolerated.

To deal with abuse I may need to capture limited amount of traffic,

this will be discarded after the abuse is dealt with.
