all-knowing-dns - Tiny DNS server for IPv6 Reverse DNS
SYNOPSIS
all-knowing-dns [--configfile <path>] [--querylog]
DESCRIPTION
AllKnowingDNS provides reverse DNS for IPv6 networks which use SLAAC (autoconf), e.g. for a /64 network.
The problem with IPv6 reverse DNS and traditional nameservers is that the nameserver requires you to provide a zone file. Assuming you want
to provide RDNS for a /64 network, you have 2**64 = 18446744073709551616 different usable IP addresses (a little less if you are using
SLAAC). Providing a zone file for that, even in a very terse notation, would consume a huge amount of disk space and could not possibly be
held in the memory of the computers we have nowadays.
AllKnowingDNS instead generates PTR and AAAA records on the fly. You only configure which network you want to serve and what your entries
should look like.
OPTIONS --configfile=path
Use path instead of /etc/all-knowing-dns.conf as configuration file.
--querylog
Enable logging every query to stdout (for debugging).
CONFIGURATION FILE (/etc/all-knowing-dns.conf)
The configuration file is wonderfully simple:
# Configuration file for AllKnowingDNS v1.3
listen 79.140.39.197
listen 2001:4d88:100e:1::3
# RaumZeitLabor
network 2001:4d88:100e:ccc0::/64
resolves to ipv6-%DIGITS%.nutzer.raumzeitlabor.de
with upstream 2001:4d88:100e:1::2
# Chaostreff
network 2001:4d88:100e:cd1::/64
resolves to ipv6-%DIGITS%.treff.noname-ev.de
This example contains all configuration directives. Let's go over them one by one:
listen address
Listens on the given address (IPv4 and IPv6 is supported) on port 53.
network network
Specifies that queries for PTR records within the given network should be answered (any query for an unconfigured network will be
answered with NXDOMAIN). You need to specify at least the resolves to directive afterwards.
resolves to address
Specifies the address to which PTR records should resolve. The address needs to contain %DIGITS% exactly once. When answering AAAA
queries, %DIGITS% will be parsed and converted back to an IPv6 address.
Example:
network 2001:4d88:100e:ccc0::/64
resolves to ipv6-%DIGITS%.nutzer.raumzeitlabor.de
Example query:
The PTR query 2001:4d88:100e:ccc0:216:eaff:fecb:826 will resolve to
ipv6-0216eafffecb0826.nutzer.raumzeitlabor.de
with upstream address
Before answering a PTR query for this network, AllKnowingDNS will ask the DNS server at address first, appending .upstream to the
query.
Example:
network 2001:4d88:100e:ccc0::/64
resolves to ipv6-%DIGITS%.nutzer.raumzeitlabor.de
with upstream 2001:4d88:100e:1::2
Example query:
The PTR query 2001:4d88:100e:ccc0:219:dbff:fe43:2ec5 will make
AllKnowingDNS ask for
5.c.e.2.3.4.e.f.f.f.b.d.9.1.2.0.0.c.c.c.e.0.0.1.
8.8.d.4.1.0.0.2.ip6.arpa.upstream. at 2001:4d88:100e:1::2
and relay the answer, if any.
DELEGATING ZONES
This section shows you how to delegate a zone in BIND9 or any DNS server with a compatible zone file syntax. To use AllKnowingDNS, you need
to delegate the appropriate .ip6.arpa zone for your network and one regular domain.
