No it isn't a typo, but it is just an example which will give you 255
clients.

From the given example '10.99.0.1', you would take the first three
octets '10.99.0' and reverse them '0.99.10', add '.in-addr.arpa' to get
'0.99.10.in-addr.arpa' and this would be the name for the reversezone.

If you require more clients, just take less octets e.g. '10.99' would
give you '99.10.in-addr.arpa'
