Recursive Resolver
A Recursive DNS Resolver setup with DNSSEC support consisting of four nodes can be reached via the hostname dns.lars-lehmann.net. The nodes support not only the classic unencrypted DNS queries on port 53, but also DoT (DNS-over-TLS) via port 853 and DoH (DNS-over-HTTPS) via port 443.
Unencrypted
For use over port 53 (unencrypted) the following Nodes are available:
DNS01
Location: Nuernberg, Germany
IPv4: 213.95.149.187
IPv6: 2001:780:250::beaf
DNS02
Location: Munich, Germany
IPv4: 213.155.91.68
IPv6: 2001:780:250:100::beaf
DNS03
Location: Frankfurth, Germany
IPv4: 134.255.247.23
IPv6: 2a0a:51c0::7fe
DNS04
Location: Duesseldorf, Germany
IPv4: 37.228.132.139
IPv6: 2a06:1c40:3::13
DoT (DNS-over-TLS)
For use with DoT there are two hostnames, the port is 853 in each case.
The hostname dns.lars-lehmann.net returns multiple hosts, possibly including hosts that are currently offline.
The hostname dns-lb.lars-lehmann.net returns only one host that is online, the availability is checked every 60 seconds.
DoH (DNS-over-HTTPS)
There are two query addresses for use with DoH.
The address https://dns.lars-lehmann.net/dns-query returns multiple hosts, possibly including hosts that are currently offline.
The hostname https://dns-lb.lars-lehmann.net/dns-query returns only one host that is online, the availability is checked every 60 seconds.
Authoritative nameserver
For DNS zone management I run the following four Authoritative nameservers with DNSSEC support.
