dnscache is a pretty weird. From the webpage at http://cr.yp.to/djbdns/dnscache.html ...
“dnscache handles dotted-decimal domain names internally, giving (e.g.) the domain name 192.48.96.2 an A record of 192.48.96.2." So it looks like dnscache will return a the IP address back for any A queries for a IP address. And it looks like it returns a basically infinite ttl. Why do you need this behaviour? I used to use dnscache many years ago, but dropped it when powerdns-recursor became available. I never noticed this “feature”, and never had anything break when it went away. > On Sep 13, 2017, at 1:17 PM, Joe Williams <[email protected]> wrote: > > Thanks for the reply Tom, I wish I knew why as well.
