ocsp.thawte.com.mydomain.net in tinydns log

Below is the excerpt of cat /service/tinydns/log/main/current, while
I'm in the middle of the attempts to set-up samba primary domain
controller running tinydns, while dnscache is running on another
machine. Domain name is fictitious, not registered. In
/service/dnscache/root/servers I've put separate entry for
mydomain.net. Am I being hacked?
