The hostname is: emailimage2.howtoburndvd.net
I have two nameservers running 9.6.0-p1. If I query ns{1,2}.linkyo.com
directly I always get an answer. If I use my own nameservers I get
mostly failures of NXDOMAIN of linkyo.net or SERVFAIL for the hostname.
DNS testers yield similar but without explanation. Would someone care
to explore and explain?
