You can easily search out entry of RDNS of the IP address which is using the diverse command from the command line. Below are some of the common examples which are actually illustrated in the commands host, dig and nslookup. Reverse database of the DNS of the web is mainly routed in an address and also in the arpa, it is also a high level of domain on the web. The ipv4 mainly uses and requires the in – addr, domain arpa and also ip6. Domain arpa is almost delegated to the ipv6. Pointer DNS type record or the PTR record is mainly the process of the reverse resolving.
Methods of finding RDNS:

Host:
Syntax:
host- IP. Address
Examples:
host 74. 125. 224. 150
150. 224. 125. 74. in - addr . arpa domain name lax 02 s 20 in the f22. 1e100. net.
Nslookup:
Syntax:
nslookup IP. Address
Examples:
nslookup 74. 125. 224. 150
150. 224. 125. 74. in - addr. Arpa and the name = lax 02 s20 . 1e 100 . net.
Dig:
Syntax:
dig- x IP. Address
Examples:
dig- x 74. 125. 224. 150+ short
Lax 02 s 20 - in - f22 . 1e 100. net.
