Class C IPv4 blocks remain one of the most in-demand digital assets for hosting providers, VPN companies, data centers, and cybersecurity firms. Because IPv4 space is limited and new allocations are no longer available, buying a Class C block typically a /24 containing 256 IP addresses requires careful planning, verification, and support from a trusted IPv4 broker. This guide explains exactly how to buy Class C IPv4 blocks safely and what to look for before finalizing a purchase.
What Is a Class C IPv4 Block?
A Class C IPv4 block historically refers to IP ranges from 192.0.0.0 to 223.255.255.255. In modern RIR terminology, Class C is not officially used anymore, but the term still refers to /24 IPv4 subnets, which include:
- 256 total IP addresses
- 251 usable IPs (after network, broadcast, and reserved addresses)
- Compact size suitable for hosting and VPN services
For businesses that need a manageable and scalable subnet, a Class C block is the ideal choice.
Why Hosting and VPN Providers Prefer Class C Blocks
Class C blocks are the backbone of many hosting, cloud, and VPN operations. Companies prefer them because they:
1. Provide clean segmentation
A /24 subnet is easy to manage, route, and monitor. Hosting companies can allocate IPs to customers without complex overhead.
2. Reduce risk of blacklisting
Unlike larger blocks, a Class C range limits reputation exposure. If an issue arises, it’s contained to a smaller subnet.
3. Offer better geolocation accuracy
VPN companies rely on IP geolocation. Class C blocks can be geolocated consistently within a target country or region.
4. Support scalability
A small hosting provider or VPN service can expand quickly without needing thousands of IPs.
How to Buy Class C IPv4 Blocks Safely
Buying IPv4 is not like buying a standard digital service. It requires verification, documentation, and RIR-compliant transfers. Follow these steps to ensure a safe, legitimate purchase.
1. Work with a Trusted IPv4 Broker
A verified broker like IPv4 Hub protects buyers from scams, blacklisted IPs, and fraudulent ownership claims. Reputable brokers offer:
- Verified IP ownership documentation
- Clean blacklist reports
- Transparent pricing
- Secure escrow transactions
- RIR-compliant transfer handling
Never buy IPv4 blocks directly from random sellers or forums.
2. Define Your Requirements Clearly
Before purchasing, determine:
- Block size: /24 (Class C), or multiple /24 blocks
- Region: ARIN (USA), RIPE (Europe), APNIC (Asia), LACNIC (LATAM)
- Use case: hosting, VPN, proxy, data center
- Budget: IPv4 prices vary based on region and reputation
This ensures you receive a block aligned with your business needs.
3. Verify the IP Block’s Cleanliness
A crucial step is confirming the IP block is not abused or blacklisted. A trustworthy broker provides:
- RBL blacklist checks
- Spamhaus and SORBS reports
- IP reputation history
- Geolocation records
Tools like IPv4 Hub’s Blacklist Checker help verify that the subnet is safe for hosting or VPN use.
4. Review Ownership Documentation
You must confirm that the seller is the legitimate holder of the IPv4 space. Your broker will validate:
- RIR registration records
- WHOIS ownership
- ASN associations
- Company identity
This prevents fraudulent transfers or disputes during the RIR process.
5. Complete the Transfer Through the Proper RIR
Depending on the region, the block will transfer through:
- ARIN (North America)
- RIPE NCC (Europe)
- APNIC (Asia-Pacific)
- LACNIC (Latin America)
Your broker will manage the transfer ticket, LOA (Letter of Authorization), and ROI (Request of Inter-RIR transfer).
6. Update Geolocation and Routing After Transfer
Once ownership is finalized, update:
- Geolocation databases
- ISP routing tables
- RIR WHOIS records
- BGP announcements
For VPN and hosting companies, correct geolocation is essential for performance and compliance.
