Interpreting a DNS report

[Ladislav Vobr]

When I look at the your reverse class report, it says one fail - Missing 
nameservers, which basically means there is a mismatch between the 
parent and the child in who should be nameservers authoritative for this 
reverse zone. Parent says ns1 and ns2, and inside the authoritative zone 
on the child you mentioned just ns1.

This kind of information should be same on parent as well as child, you 
might face interminent problems with it.

BTW: you should really have more than single server, this is a must. You 
can somehow register with single one "pretending two", as you did, but 
at the end this will really turn against you... (and your users)
