Helo,

we have 2 DNS servers in 2 different datacenters, running since years 
without problem. So I think it's not a problem from us, that both our 
DNS cannot resolve a simple
# dig -x 212.186.228.42

We just get a timeout, but when I try from different internet accesses, 
I get a resolve:
42.228.186.212.in-addr.arpa. 86400 IN   PTR     vcoe-exchange.vcoe.at.

Can someone show me where to search for the problem?
