IPv4 地址采购指南
Acquiring IPv4 blocks requires navigating Regional Internet Registry (RIR) policies. ISP coordinates the full acquisition process — from requirement definition and resource matching through verification, documentation and final transfer.
- Define requirements — block size, RIR region and budget.
- Resource matching — identify clean, transferable blocks.
- Verification — ownership, route history and IP reputation.
- Documentation — transfer agreement and registry paperwork.
- Completion — RIR transfer and routing handover.

五大 RIR 注册局准入条件
Each RIR applies its own transfer policies and eligibility criteria. Buyers typically must demonstrate a justified need for address space and meet the receiving RIR's requirements. Our team assesses your eligibility and recommends the most suitable transfer path.
官方过户资格尽调
Eligibility depends on the source and destination RIR, the block's history and your organization's registration status. We evaluate these factors up front to ensure a smooth transaction.
IP 信誉与黑名单清洗
Before purchase, we verify that a block is clean — checking blacklist status, abuse history and BGP routing history — so you receive addresses suitable for production use.
