Zone manager with friendly words for IPs
Assign a zone to your
/64 block and give friendly names like:
to your jails, virtual machines, self-hosted services, ...
This is deployed for the yggdrasil experimental network on
In order to get a name assigned to you, execute from an yggdrasil enabled system:
This operation is idempotent and the three words are derived from your client's IP address (*).
(*): Since the space of words is significantly smaller than that of IPs, this service requires some state and assigns the combination of words on a first-come first-served basis. The algorithm further iterates to try to find a name for an IP but makes no promises of this being possible. Do host your own!
Use this to, for example, echo back an IPv4 as an
A record on IPv6-only
environments that have DNS64 and NAT64 setup.
That way, your local DNS will add
AAAA records that will enable your
IPv6-only machines to connect to raw IPv4 addresses without domain.
This is deployed on
echo.dnslab.evilham.com(**), use like this:
That will return an
A record with
127.0.0.8 as an address.
In DNS64+NAT64 environemnts you'll also see a
AAAA record with
embedded in your NAT64's IPv6 prefix.
UPDATE: because reasons this also supports v6 now. As an alternative to ':' in v6, you can use '-' or '.'. Enjoy. (reasons: https://ungleich.ch/u/blog/has-a-name-for-every-ipv6-address/)
(**): Hosted on a best-effort basis :-). Host your own if you want to depend on it.
