Question 1

How can my data center get IPv4 addresses for tenants without an RIR allocation?

IPv4Center · Accepted Answer

You can lease or purchase IPv4 blocks directly through IPv4Center's marketplace without waiting for an RIR allocation. Leased blocks come with LOA documentation that authorizes your ASN to announce them. Purchased blocks are fully transferred to your organization through the relevant RIR, giving you permanent ownership.

Question 2

Can my tenants use leased IPv4 addresses for their own services?

IPv4Center · Accepted Answer

Yes. Tenants can use leased blocks for any legitimate purpose including web hosting, email, VPN, and SaaS applications. We provide sub-LOA documentation so your tenants can prove authorization to upstream providers. Sub-allocation and re-assignment to tenants is fully permitted under our terms.

Question 3

How does rDNS delegation work for data center blocks?

IPv4Center · Accepted Answer

We delegate the reverse DNS zone for your entire block to your nameservers, giving you full control over PTR records. You can then manage rDNS centrally or further delegate zones to individual tenants. Changes propagate within minutes, and we support both standard and RFC 2317 classless delegation for blocks smaller than /24.

Question 4

Can I sub-allocate or resell leased IPv4 addresses to my tenants?

IPv4Center · Accepted Answer

Yes. Data center operators can sub-allocate leased blocks to their colocation tenants and managed hosting customers. You maintain a single lease with IPv4Center while distributing addresses to tenants as needed. We provide the necessary SWIP or rwhois records to document sub-allocations.

Question 5

How do you ensure accurate geolocation for my data center's IP blocks?

IPv4Center · Accepted Answer

We configure geofeed files (RFC 9092) and submit geolocation corrections to all major geolocation databases including MaxMind, IP2Location, and DB-IP. This ensures your tenants' services resolve to the correct city and region. Geolocation updates typically propagate within 2-4 weeks across all major providers.

Question 6

Should a data center lease or buy IPv4 addresses?

IPv4Center · Accepted Answer

It depends on your business model. Purchasing makes sense for core infrastructure and long-term tenants — blocks become balance sheet assets and eliminate recurring costs. Leasing is ideal for new facilities still building occupancy, overflow capacity, and short-term tenant needs. Most operators use a combination of both.

Question 7

How quickly can we provision new IPv4 blocks?

IPv4Center · Accepted Answer

Leased blocks are provisioned within 24-48 hours, including LOA documentation and RPKI records. For purchased blocks, the inter-RIR transfer takes 5-14 business days depending on the registry. We handle all transfer paperwork, WHOIS updates, and routing registry objects so you can focus on your operations.

Question 8

Do you support all five RIR regions?

IPv4Center · Accepted Answer

Yes. IPv4Center operates across RIPE NCC, ARIN, APNIC, LACNIC, and AFRINIC. Whether your data centers are in North America, Europe, Asia-Pacific, Latin America, or Africa, we can provide locally-registered IPv4 blocks that comply with each region's transfer policies.
