aka The registry contains:
dn42.
The registry is a git repository, hosted here: https://git.dn42.dev/dn42/registry.git, Changes to the registry are managed by submitting pull requests to the repository, these are then reviewed by the registry maintainers before acceptance.
dn42 uses some names and numbers, which are declared in the registry. Whenever possible, we try to stick to names and numbers that do not conflict with the ICANN-net or other networks similar to dn42, for instance by using private numbers space.
dn42 uses 172.20.0.0/14 for IPv4.
For IPv6, we use ULA (that is, fd00::/8).
See also the howto page covering the DN42 address space.
Since June 2014, dn42 is using the 4242420000-4242429999 ASN range for allocations. This range is further subdivided:
If you are running a project similar to dn42, please use another range of ASN. The "sub-allocations" range is meant for dn42 users willing to have administrative control over a small, consecutive range of ASN (e.g. to use them directly or to distribute them).
Note that currently, most AS are using one of the legacy ASN range (and will probably continue to do so, as renumbering is painful). See the FAQ for a discussion on AS ranges.
dn42 uses the dn42.
TLD, which is not present in the root DNS zone of the ICANN-net. For details, see DNS.
Note that other TLDs should also be usable from dn42, most notably from Freifunk and ChaosVPN. A tentative list is available at External DNS.
The gitea instance hosting the registry has an associated Drone CI/CD service:
Users are free to add drone pipelines to their own repositories. Repositories can be enabled using the Drone server user interface.
A telegram whois bot owned by @Oxygen233 is hosted on @DN42WhoisBot.
Privacy mode is enabled, please call the bot with @DN42WhoisBot when necessary.
https://explorer.burble.dn42/ (https://explorer.burble.com/ via clearnet) provides a web interface and REST API for querying the DN42 registry.
The service is provided by dn42regsrv which can also be run locally.
See the page on Registry Authentication
There is also a DNS-based interface to query AS information from the registry. The DNS zone is asn.dn42
.
Mirrors are hosted at asn.grmml.dn42
and asn.lorkep.dn42
.
Example:
$ dig +short AS4242420000.asn.dn42 TXT
"4242420000 | DN42 | dn42 | | PYROPETER-AS PyroPeters AS"
The Python code for generating the zone from the registry is available on the monotone repository.
An alternative version to query the registry is it ip.catgirls.dn42
(IPv6 only) (Source code https://git.catgirls.systems/famfo/ipinfo). Note: if there is no route
/route6
object for the inetnum
/inet6num
, the ip address will not be found.
This can be used together with mtr
using the --ipinfo_provider4
and --ipinfo_provider6
flags (mtr has to be build from source for that, there hasn't been a release in a while).
Example:
$ dig +short TXT as4242421411.ip.catgirls.dn42
"4242421411 | C4TG1RL5-MNT | 172.20.0.81/32 | 172.23.196.32/27 | 172.20.0.80/32 | fd42:d42:d42:2080::/64 | fd42:deca:fbad::/48 | fd42:d42:d42:81::/64"
$ dig +short TXT 32.196.23.172.ip.catgirls.dn42
"4242421411 | C4TG1RL5-MNT | 172.20.0.81/32 | 172.23.196.32/27 | 172.20.0.80/32 | fd42:d42:d42:2080::/64 | fd42:deca:fbad::/48 | fd42:d42:d42:81::/64"
$ dig +short TXT 1.d.a.b.f.a.c.e.d.2.4.d.f.ip.catgirls.dn42
"4242421411 | C4TG1RL5-MNT | 172.20.0.81/32 | 172.23.196.32/27 | 172.20.0.80/32 | fd42:d42:d42:2080::/64 | fd42:deca:fbad::/48 | fd42:d42:d42:81::/64"
The idea comes from the guys at cymru.com, who provide this service for the Internet (e.g. AS1.asn.cymru.com
), see https://www.team-cymru.org/Services/ip-to-asn.html#dns
We have anycast IPv4 and IPv6, both reachable under whois.dn42. IPs are 172.22.0.43 respective fd42:d42:d42:43::1. Please consider joining these anycast-adresses when you setup your server. Updates every 1 hour would be nice for a start.

You can then use whois without specifying the server. Works at least with Marco d'Itri's whois client.
cd /home/some/path/to/store/branch
sudo aptitude install ruby rubygems
sudo gem install netaddr
cd whoisd/ruby
sudo ruby whoisd.rb nobody
Note: this service is in beta testing, use at your own risk. https://whois.rest.dn42/
