Hello :)

Reverse DNS uses pointer records (PTR) to convert IP addresses into domain names. This is the opposite of forward DNS, which uses A records to convert domain names into IP addresses. This is documented at:

RDNS for Bind

However, typically you must consult with your hosting provider or data center so they can setup the reverse DNS for you.

Thank you.

SWIP (Shared WHOIS Project) is the process that ISP's use to make their submissions of IP space reassignment information to WHOIS.

Thank you.

SWIP (Shared WHOIS Project)
Thanks Michael.

Then x ISP ABC = owner of range 22.22.22.1 to 22.22.22.256 (by example)

Then when a little company rent a server,
the ISP ABC reassigned [WHOIS/INFO OWNER]
of range 22.22.22.1 to 22.22.22.5
becouse IPs from 22.22.22.1 to 22.22.22.5 now is used by
"little company"

This is SWIP?
