That's straightforward. Dnsmasq gets a query for 
62.75.115.213.in-addr.arpa, sends it upstream, gets an answer which 
isn't signed, and determines that it's insecure, then returns the 
answer. The last line is as it is because a PTR RR for 
62.75.115.213.in-addr.arpa has been parsed into the triple
(213.115.75.62, static-213-115-75-62.sme.bredbandsbolaget.se, 
reverse-mapping)
for storage in the dnsmasq cache, which is not a general RR cache, but a 
cache of domain-names against IP addresses, with some extensions for 
CNAMEs, and now more extensions for DNSKEYs DSs and RRSIGs.

Cheers,

Simon.
