Shared Whois Project
Encyclopedia
The Shared Whois Project (SWIP) is the process used to submit, maintain and update information to ensure up-to-date and efficient maintenance of WHOIS
records, as structured in RFC 1491. The process updates WHOIS to contain information regarding what organization is using a specific IP address
, or a specific block of addresses. Additionally, it provides means to track the use of an organization's current allocations of IP addresses, so that additional allocation of IP
addresses may be justified and usage reports or case studies may be done.
SWIP must be used within seven days of any reassignment of an IP address space to a downstream customer to:
In contrast, an organization is not required to submit a SWIP template for fewer than eight IP addresses.
Allocations, assignments or reassignments of blocks of 8,192 addresses and more must be approved by ARIN
beforehand. Companies assigned a blocks of 65,536 addresses or more will be responsible for maintaining all IN-ADDR.ARPA domain
records for their customers.
There are two types of registration. The first is an allocation, for blocks of IP addresses which will later be reallocated or reassigned to third parties. The second is an assignment, for blocks that will not be reassigned, or the recipient is an end-user

WHOIS
WHOIS is a query and response protocol that is widely used for querying databases that store the registered users or assignees of an Internet resource, such as a domain name, an IP address block, or an autonomous system, but is also used for a wider range of other information. The protocol stores...

SWIP must be used within seven days of any reassignment of an IP address space to a downstream customer to:
- Provide new reassignments of blocks of eight or more IP addresses
- Delete existing reassignments, or
- Modify data connected to existing reassignments.

A top-level domain is one of the domains at the highest level in the hierarchical Domain Name System of the Internet. The top-level domain names are installed in the root zone of the name space. For all domains in lower levels, it is the last part of the domain name, that is, the last label of a...
