B2B IPv4 address resources
Lease IPv4 Address Blocks with Routing and Use-Case Review
Request an IPv4 address block for a China-based or China-facing deployment, with CIDR size, lease term, intended use, routing model and compliance expectations documented from the start.
Business address resources
A routed resource requires accountability.
Cidriva frames IPv4 leasing as a B2B address-space request with documented use, routing and operating responsibilities.
Supplier-network model
Describe the required network-supplier environment, LOA, IRR/RPKI, rDNS and geolocation expectations for technical review.
Compliance context
Intended use, KYC, reputation requirements and abuse-handling responsibilities belong in the scope.
Address block checklist
Six inputs for an IPv4 proposal.
Provide these inputs so sales can qualify current availability and the operational model.
256 addresses
Address counts are a CIDR reference only. They do not indicate current block availability.
- CIDR size
- Required block size, whether adjacent ranges matter, and the expected lease term.
- Region / RIR
- Target geography, regulatory context and any specific registry requirement.
- Intended use
- Service type, traffic pattern, end-user model and prohibited-use controls.
- Network delivery
- Which communication network supplier delivers the block, what authorization is required, and how routing changes are managed inside that supplier environment.
- Operations
- rDNS, geolocation, reputation monitoring, incident contact and abuse-response workflow.
- Verification
- Business identity, authority to use the resource and any upstream or platform requirements.
Review path
Request. Verify. Define. Quote.
Address reputation is assessed against the stated use case, checks and acceptance criteria.
Written scope
Step 03- Availability status
- Routing responsibilities
- Operational services
- Commercial terms
Current block availability, routing responsibilities, reputation checks and commercial terms are confirmed after technical and policy review. For China-facing infrastructure, compare location and route assumptions in the China connectivity solution assessment.
IPv4 leasing FAQ
Before you request.
What IPv4 block size can I request?
Provide the preferred CIDR size or address count, whether adjacent ranges matter and the expected lease term. Current availability and the applicable resource scope are confirmed only after review.
How is the address block delivered?
Address blocks are delivered within the selected communication network supplier's routing environment. The written proposal records the supplier environment, prefix, authorization and operational responsibilities.
What lease, KYC and use-case information is required?
Include the requested term, target region, intended service, traffic and end-user model, business identity and any upstream or platform requirements.
How is address reputation evaluated?
Reputation is time-sensitive and use-case dependent. Define the data sources, checks and acceptance criteria required for your deployment.
How are LOA, IRR, RPKI or rDNS requirements handled?
Include them in the request. The proposal confirms applicable capability, dependencies and responsibility for the specific resource and routing model.
