Who buys IPv4 blocks
- Hosting and email infrastructure
- Shared hosting, SSL-per-IP setups and dedicated SMTP servers where clean reputation drives inbox placement. Typical: /24 to /22.
- ISPs and telecoms
- Customer CPE, carrier-grade NAT and public services, sometimes under regulatory requirement to hold IPv4. Typical: /22 to /19.
- Enterprise multi-homing
- Provider-independent space for multi-homing and disaster recovery without vendor lock-in. Typical: /24 to /23.

IPv4 allocation FAQ
IPv4 transfers run on the secondary market: pricing depends on block size, reputation and current supply/demand, and shifts from one transfer to the next. We quote per request rather than publish a rate card. Ask through the form and get a firm figure.
Yes. We sponsor your allocation under our LIR membership, or you can register as a RIPE LIR yourself. Sponsored blocks stay in the RIPE database under your organization's details, administered through our LIR account.
2-4 weeks from signed agreement to activation: documentation review (3-5 days), RIPE transfer submission (1-2 days), RIPE NCC processing (7-14 days), activation (1-2 days). Incomplete documentation adds delay.
Reputation tracks whether a block was used for spam or abuse; we check every block against major blocklists before transfer. IPv4 addresses are transferable assets under RIPE policy, but you must wait 6 months after receiving a transfer before initiating another.
