[Pdns-users] DDOS TKEY request

[Giorgio Lardone]

Hi

I have detected a high traffic on our DNS servers since yesterday 
(Dnsdist + Powerdns) of queries for non-existent records similar to 
"_.domainname.tld"


TKEY request but no TKEY RR found    1154    49.8%
More than one TKEY record found in query    577    24.9%
TKEY record has no or invalid content (invalid packet)    577    24.9%

Have you ever had a similar experience?

Do you suggest inserting/modifying some parameter in the DNSdist and/or 
PowerDNS configuration?

Thanks for any suggestion!

Best regards,
Giorgio
