ouch - this is all quite confusing to me.
if you have allocated a portion of space to a client, set it up as follows:
assumed: you are responsible for 251.218.205.in-addr.arpa
assumed: your client runs their own DNS for domain.com
assumed: your client is going to run reverse for the subnet
in the forward zone file for domain.com:
somename IN A 184.108.40.206
someother IN A 220.127.116.11
160 IN PTR somename.domain.com.
161 IN PTR someother.domain.com.
in your IN-ADDR.ARPA file for the zone:
160 IN CNAME 160.rev.domain.com.
161 IN CNAME 161.rev.domain.com.
this allows you to refer all reverse lookups to the NS responsible for
domain.com, and it also allows them to keep them updated. i've run DNS like
this for years.
