# *note : For How to write for reverse resolving, Write network address reversely like below 10.20.0.0/24 For the case of 10.20.0.0/24
network address ⇒ 10.20.0.0
network range ⇒ 10.20.0.0 - 10.20.0.255
how to write ⇒ 0.20.10.in-addr.arpa

For the case of 172.16.0.80/29
network address ⇒ 172.16.0.80
network range ⇒ 172.16.0.80 - 172.16.0.87
how to write ⇒ 80.0.16.172.in-addr.arpa
