Colocation & IPv4: An Overview
Colocation (colo) facilities have become indispensable for businesses looking to secure data center space while avoiding the hassle and expense of building their own. One thing these setups all have in common: they require careful IP address management. Even with IPv6 gaining ground, IPv4 remains standard for most public connectivity, which keeps demand high.
With IPv4 addresses in short supply, companies relying on colocation—whether ISPs, IT teams, or network architects—have to plan carefully. Securing and handling these addresses is a real concern, and not something you can ignore if uptime and scalability matter for your business.

Why IPv4 Matters in Colocation
If your infrastructure needs to be reachable from the wider internet, a pool of routable IPv4 addresses is non-negotiable. Colocation setups generally fall into a few approaches:
- Bring Your Own IPs (BYOIP): You use your own IPv4 addresses and announce them using your ASN, with routes advertised through the colo’s upstream providers.
- Provider-Assigned IPs: The data center allocates space from its own pool, managing the addresses for you.
- Hybrid: Sometimes it makes sense to combine both, depending on the services or applications in play.
Each option affects how much you pay, how much you can scale, and how much control you keep over your network.
IPv4 Address Management Options
Before you pick a colocation provider, map out your IPv4 address strategy. These are some of the main routes companies take:
- Lease IPv4 addresses: Good for growth spikes or projects with an uncertain time frame. Leasing means less money up front and you only pay for what you use.
- Buy IPv4 addresses: If you’re in it for the long haul, owning your addresses makes costs more predictable and gives you total routing control.
- Use provider IP assignments: The simplest approach, but it can get tricky if you’re expanding across locations or want to avoid vendor lock-in.
| Option | Pros | Cons | Best For |
|---|---|---|---|
| Lease IPv4 | Low upfront cost, flexible, quick provisioning | Ongoing fees, potential for reassignment | Startups, projects, burst scaling |
| Buy IPv4 | Full control, predictable cost, asset ownership | Higher initial expense, market volatility | Enterprises, ISPs, long-term planning |
| Provider Assigned | Easy setup, managed support | Limited portability, dependency on provider | Small businesses, pilot projects |
Colocation vs. Cloud: IPv4 Allocation Compared
The way you handle IPv4 addresses is quite different in a colocation versus a cloud hosting scenario:
| Aspect | Colocation | Cloud Hosting |
|---|---|---|
| IP Address Ownership | Own, lease, or provider-assigned | Provider-assigned, typically non-portable |
| Flexibility & Control | High, with BYOIP possible | Limited, as addresses tied to provider |
| Scalability | Depends on IP acquisition strategy | Instant scaling, but address limitations |
| Long-term Cost | Potentially lower if buying IPv4 | Recurring fees, no asset accumulation |
Colocation setups give you much more room to maneuver, especially if you need to control routing or move between providers.
Best Practices for IPv4 in Colocation
- Plan ahead: Figure out what you need now and what you’ll need later. Buying too much ties up capital; too little holds you back.
- Document your allocations: Detailed records prevent headaches. Knowing who’s using what, and where, is key for troubleshooting and audits.
- Coordinate with your provider: Double-check that BYOIP is supported and clarify how routes and security will be handled.
- Monitor utilization: Tools like RIR portals or IPAM platforms—free or commercial—can help you keep tabs on usage and spot waste.
- Implement security measures: Don’t overlook basics like firewalls, access controls, and DDoS defense. IPs can become a target.
Tips for Sourcing IPv4 in Colocation Environments
- Understand current market rates: As of early 2024, expect a /24 block to run between $38,000 and $45,000 USD. Leasing often lands in the $0.60 to $1.20 per IP per month range. Prices shift, so keep an eye on trends.
- Work with trusted partners: Go with established platforms that offer transfer assistance, anti-fraud protections, and escrow—like IP4 Market.
- Consider future scalability: Leasing makes sense for short-term bursts, but if you’re planning several years ahead, buying could save money in the end.
- Check compliance: Make sure all transfers follow RIR rules (ARIN, RIPE NCC, APNIC, etc.), and loop in your colocation team early to avoid routing issues down the line.
FAQ & Key Takeaways
Frequently Asked Questions
- Can I bring my own IPv4 addresses to a colocation facility?
You can, but support for BYOIP and their BGP policies will vary, so always check with your provider beforehand. - Should I buy or lease IPv4 addresses?
Leasing is handy for unpredictable or short-lived needs; buying is usually better if you need stability or independence. - What should I look for in an IPv4 marketplace?
Look for vetted sellers, help with the transfer process, and clear, upfront pricing—IP4 Market is one of the better-known options.
