Replying to [comment:4 Sebastian]:
> The TTL of the entries of those hosts is set to something very
unreasonably low. If you are in any way responsible for the relays
mentioned above, please fix their DNS config.
This ticket is not about rDNS entries of specific relays, these were
merely examples, AFAIK these relays left the tor network a while ago:
https://lists.torproject.org/pipermail/tor-
relays/2016-February/008807.html
> While the reverse dns for these IPs is set, forward entries don't exist.
Perhaps this is an additional check that onionoo does (and I think it
probably should do).
If onionoo requires PTR and A DNS records to match please add that
information to the description, currently it does not mention that in any
way:
https://onionoo.torproject.org/protocol.html#details :
{{{
host_name string optional
Host name as found in a reverse DNS lookup of the relay IP address. This
field is updated at most once in 12 hours, unless the relay IP address
changes. Omitted if the relay IP address was not looked up or if no lookup
request was successful yet.
}}}
I care about rDNS records (even if PTR and A records don't match) because
I'd like to use them for group detection for ornetradar and it is
apparently very common that providers do not have A records for PTR
records.
