Hi,
Is anyone aware of an existing Python/PHP library/function that finds
the 'best' zone for a given record?
For example, the following PTR records and DNS zones would be matched
correctly:
- DNS zone '80.10.in-addr.arpa.'
- DNS zone '40.10.in-addr.arpa.'
- PTR record '20.1.80.10.in-addr.arpa.'
- PTR record '12.1.40.10.in-addr.arpa.'
I came across
https://github.com/PowerDNS/pdns/blob/3ba8b76c8e55fd14397ef73e4fa1e29a92cc9097/pdns/ueberbackend.cc#L320
(`UeberBackend::getAuth`), which does the same.
It was used for `set-ptr` until its deprecation:
https://github.com/PowerDNS/pdns/commit/65e921299bf55d5c420e2c7aae1b66c08865cd87#diff-ac1312d4611881e640a571bbe99180d88c382614a910c22ab0b527eddf38d00bL568
However, it seems like `set-ptr` was partly deprecated (?) due to
`UeberBackend::getAuth` not being fully accurate, according to
https://github.com/PowerDNS/pdns/issues/4656#issuecomment-445736542
With kind regards,
William Edwards
