about reverse lookup specifications

[willbase]

Hello,

I would like to know the specifications of Fortigate, when is a reverse lookup done when a name resolution query is made to a particular domain?

example:

■forward lookup

FQDN : aaa.com

IP : 54.11.11.11

■reverse lookup

FQDN : bbb.com

IP : 54.11.11.11

Is there a possibility that different name resolution will be performed even if the IP address is the same?
Also, if there is a way to check reverse lookups with a command, please let me know
