In today’s hyper-connected world, your business’s digital footprint is as important as your physical presence. One crucial part of that footprint is your IP address, the unique identifier that connects your organization to the internet. While many companies still view IP addresses as something they need to purchase and manage themselves, an increasing number are discovering a safer, more efficient approach: professionally managed leased IPs.
CGNAT Still Matters But It’s Not Enough
Carrier-Grade NAT (CGNAT) remains a practical tool for conserving IPv4 resources, especially in mobile and residential broadband networks with millions of low-usage subscribers. By allowing thousands of users to share a single public IPv4 address, CGNAT has enabled growth without immediate IPv6 transition.
However, its shortcomings are becoming harder to ignore. Latency increases as NAT translation overhead grows under heavy load, throughput declines, and application compatibility breaks down. Services such as VoIP, online gaming, VPNs, and smart home applications often fail in shared IP environments.
Compliance makes matters worse. In markets like India and Singapore, operators are required to maintain detailed port- and timestamp-level logging for months or years. One study estimated that 10,000 CGNAT users could generate 4.7 TB of logs annually. The infrastructure and administrative overhead quickly erode the cost benefits CGNAT once promised.
Leasing IPv4 as a Strategic Alternative
Instead of relying solely on CGNAT or investing heavily in IPv4 acquisitions, telecoms are increasingly turning to IPv4 leasing as a flexible, scalable solution. Leasing allows operators to access clean, reputation-safe IPs on demand, restoring end-to-end connectivity for the services and customers that require it.
Through IPXO’s platform, operators gain access to IPv4 resources from multiple Regional Internet Registries (RIRs), with built-in tools for RPKI delegation, geolocation updates, and reputation monitoring. This approach not only simplifies management but also accelerates service rollouts, improves customer experience, and aligns with regulatory requirements.
Case Example: Leasing in Action
The trend is visible across Asia-Pacific. According to APNIC’s 2024 survey, 15% of organizations have already purchased or leased IPv4 addresses, with East Asia leading in adoption.
One Southeast Asian ISP with over one million subscribers faced mounting CGNAT-related complaints, from latency to broken peer-to-peer services. Rather than expand CGNAT capacity or purchase costly IPv4 blocks, the operator leased 50,000 addresses through a centralized marketplace. The IPs were allocated to business customers, remote workers, and heavy-use residential subscribers.
The impact was immediate: within six months, CGNAT-related support tickets fell by 35%, network performance improved, and the operator introduced new premium service tiers with dedicated public IPs.
Beyond Cost Savings: Operational Flexibility
IPv4 leasing doesn’t just reduce CapEx – it unlocks operational agility. Clean, reputation-checked addresses are instantly deployable and can be integrated into hybrid infrastructures. With BYOIP (Bring Your Own IP), leased resources can extend into AWS, Azure, and Google Cloud environments, ensuring consistency across on-prem and cloud deployments.
For operators rolling out 5G, IoT, or edge services, the ability to scale IPs without ownership burdens is a major advantage. Clean leased space ensures smooth interconnects and reliable performance, even for emerging real-time workloads.
