[DNSSEC-Ops] DNSSEC missing NSEC records

[Brian Somers (brsomers)]

Hi,

Hopefully this email will reach a human.  In summary, I am querying your nameservers with a query who’s response is a negative result.  The negative result does not supply correct NSEC proof, so the result is being thrown away.  According to your web page at https://afrinic.net/dnssec, you are using standard tools, so perhaps an upgrade is necessary?

The details:


$ dig +dnssec PTR 55.210.179.2.in-addr.arpa



; <<>> DiG 9.10.3-P4-Debian <<>> +dnssec PTR 55.210.179.2.in-addr.arpa

The response correctly denies the existence of 179.2.in-addr.arpa and everything below it, but it does not deny the existence of *.2.in-addr.arpa (the wildcard record) which, if present, would expand to 55.210.179.2.in-addr.arpa.

This can be seen also here: https://dnssec-analyzer.verisignlabs.com/55.210.179.2.in-addr.arpa
and here: http://dnsviz.net/d/55.210.179.2.in-addr.arpa/dnssec/

Are there any plans to address this issue?  Thanks for your time.
