Shared Whois Project

Shared Whois Project is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Shared Whois Project rather than just read about it. In short: 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.

Key takeaways

Shared Whois Project belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Shared Whois Project to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Shared Whois Project from memory before moving on to harder problems.

Reference excerpt

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:

Provide new reassignments of blocks of eight or more IP addresses Delete existing reassignments, or Modify data connected to existing reassignments. 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 (greater than a /19 block) must be approved by ARIN beforehand. Companies assigned a block 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.

Worked examples

Example 1 — a first encounter with Shared Whois Project

Start with the simplest possible case. Write down what Shared Whois Project claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Shared Whois Project before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Shared Whois Project ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Shared Whois Project

In research: Shared Whois Project appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Shared Whois Project in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Shared Whois Project is common in secondary-school and first-year university syllabi. It links to neighbouring topics Internet Standards, Internet protocols, so understanding it makes those chapters shorter.
In everyday life: Look for Shared Whois Project outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
