The difference between a smooth IPv4 transaction and a headache often comes down to the paperwork. A well-built lease or purchase agreement sets expectations, protects both parties, and keeps the transfer compliant from day one. This guide breaks down how to approach both leasing and purchasing IPv4 address agreements, and what key elements should always be included.
Why IPv4 Agreement Structure Matters
An IPv4 transaction involves ownership rights, usage conditions, legal protections, and ongoing responsibilities. A well-structured agreement ensures:
- Clarity: Both parties understand their rights and obligations.
- Compliance: The transfer or lease adheres to RIR policies and regional regulations.
- Security: Assets are protected from misuse, fraud, or unauthorized transfers.
- Financial Protection: Payment terms, renewal options, and liability clauses are clearly defined.
Structuring a Lease Agreement for IPv4 Addresses
Leasing is often the best choice for organizations needing short- to mid-term access to IPv4 space without a large upfront investment. A properly structured lease agreement balances flexibility with protection for both lessor and lessee. Contact us or check out our FAQ for more info on leasing IPv4 addresses.
1. Define the Lease Term
Specify the start and end dates clearly. Common lease terms range from 6 months to 3 years, with options for renewal. Renewal clauses should outline how extensions will be handled: automatically, by written agreement, or through renegotiation.
2. Outline Usage Rights and Restrictions
The agreement should state how the lessee can use the IPv4 space, including:
- Whether the addresses can be used globally or are limited by region.
- Any restrictions on subleasing or reassignment.
- Compliance with RIR policies and applicable laws.
3. Include Service-Level Expectations
Although leasing often involves less ongoing responsibility than ownership, both parties should agree on:
- Maintenance responsibilities (e.g., ensuring routeability, updating WHOIS records).
- Requirements for maintaining reputation (e.g., prohibiting spam or malicious activity).
- Conditions for revocation in case of policy violations.
4. Specify Payment Terms
Define payment amount, frequency (monthly, quarterly, annually), and accepted payment methods. Include late payment penalties or terms for early termination, if applicable.
5. Add Security, Liability, and Indemnification Clauses
Protect both parties by outlining:
- Liability limits for misuse of the leased IPs.
- Procedures if the addresses become blacklisted or subject to legal action.
- Indemnification clauses to shield each party from third-party claims.
Structuring a Purchase Agreement for IPv4 Addresses
If long-term ownership, asset control, or predictable costs are the priority, purchasing IPv4 space is often the better route. A purchase agreement should clearly transfer ownership rights and ensure full legal compliance.
1. Identify the Parties and the IP Block
Include legal names and contact details for both buyer and seller, as well as precise details of the IPv4 block (range, size, and any relevant registry information).
2. Define Transfer Scope and Terms
Clarify the nature of the transaction, including:
- Whether the transfer is intra-RIR (within the same region) or inter-RIR (between regions).
- Any conditions precedent to transfer, such as RIR pre-approval or payment milestones.
- Obligations for completing RIR documentation and WHOIS updates.
3. Establish Payment and Escrow Terms
Since IPv4 purchases often involve significant sums, escrow is strongly recommended. Specify:
- Total purchase price and payment schedule.
- Escrow provider and conditions for releasing funds.
- Remedies for payment delays or default.
4. Warranty and Representations
The seller should warrant that:
- They are the rightful owner and have full authority to transfer the IP block.
- The addresses are free of encumbrances, disputes, or third-party claims.
- The IP block has not been used for unlawful activities or blacklisted.
5. Include Post-Transfer Support and Obligations
Some agreements include a transition period where the seller assists with technical handover, documentation updates, or RIR coordination. Outline the duration and scope of any post-transfer support.
