Non resolving i.zdnscloud.com/j.zdnscloud.com

[Raymond Dijkxhoorn]

Hi!

Perhaps this has been discussed before but could not find a pointer in the 
list server archive yet.

Does anyone have pointers why two nameserver records inside many TLD's are 
stale/broken for some timne now.

i.zdnscloud.com/j.zdnscloud.com dont have A/AAAA records. But are listed 
inside a whole set of TLD's.
