> In some environments, the entire container subnet may not be used exclusively by containers (ie the YARN nodemanager host IPs may also be part of the larger subnet). 
> As a result, the reverse lookup zones created by the YARN Registry DNS server may not match those created on the forwarders.
> For example:
> Network: 172.27.0.0
> Subnet: 255.255.248.0
> Hosts:
> 0.27.172.in-addr.arpa
> 1.27.172.in-addr.arpa
> 2.27.172.in-addr.arpa
> 3.27.172.in-addr.arpa
> Containers
> 4.27.172.in-addr.arpa
> 5.27.172.in-addr.arpa
> 6.27.172.in-addr.arpa
> 7.27.172.in-addr.arpa
> YARN Registry DNS only allows for creating (as the total IP count is greater than 256):
> 27.172.in-addr.arpa
> Provide configuration to further subdivide the subnets.
