You pay a premium for your business internet. Dedicated fiber, SLA guarantees, static IPs. You expect the best. But here’s the dirty secret the telcos won’t tell you: Your business is likely stuck on IPv4 — the internet protocol from 1981 — while your home connection, on the exact same fiber line, already runs on IPv6, the modern standard.
I discovered this firsthand when a Telus customer in Canada told me his story. He has a home fiber plan and a business fiber plan from the same ISP. Same physical line. Same modem. Same DMARC point. His home network gets IPv6. His business network? IPv4 only. He pays three times more for the business plan and gets an older, more constrained, and increasingly expensive protocol.
This isn’t a glitch. It’s a systemic failure of enterprise IT risk aversion.
IPv6 adoption crossed 50% globally last month, according to Google’s statistics. That’s a milestone. But the adoption is lopsided in a way that turns everything we assume about technology adoption on its head. Home users — the ones who pay less, get less support, and are typically late adopters — are now the vanguard of internet infrastructure evolution. Businesses, the supposed early adopters who pay for the latest and greatest, are stuck with the legacy.
Why? Because enterprise IT departments are terrified of breaking something. They’ve built their internal networks, their security appliances, their VPNs, and their monitoring tools around IPv4. Upgrading to IPv6 means testing every single piece of software, every firewall rule, every remote access solution. It’s a headache. So they delay. And they delay. And they tell themselves that IPv4 works fine.
But here’s the problem: IPv4 is running out of address space. The remaining blocks are traded like real estate. ISPs are forced to use Carrier-Grade NAT (CGNAT) for IPv4, which means you share a public IP with dozens of other customers. That breaks VPNs, gaming, remote access, and any service that requires a direct connection. Your business’s critical applications are being hamstrung by a protocol that was designed when the internet had 10,000 hosts.
Meanwhile, home users get IPv6. Because ISPs realized that deploying IPv6 to residential customers is easy — they control the modems, the firmware, the CPE. Business customers, on the other hand, often have their own routers, their own firewalls, their own custom configurations. The ISP can’t just flip a switch without risking a support nightmare. So they don’t. They leave business customers on the old protocol, justifying it with ‘stability’ and ‘backward compatibility.’
Stability is just a polite word for stagnation.
This isn’t just about networking. It’s a parable for every enterprise technology decision. The same dynamic plays out in enterprise software, cloud migration, and security updates. The more you pay, the more locked in you are. The more complex your environment, the more afraid you are to change. The result? The consumer internet — messy, chaotic, and constantly upgrading — actually runs on newer, better infrastructure than the pristine, locked-down corporate network.
I’ve seen IT managers who are proud of their IPv4-only network. They call it ‘mature.’ They call it ‘stable.’ They call it ‘proven.’ But what they’re really saying is, ‘We’re too afraid to move.’ And that fear is costing them. Every new application, every cloud service, every IoT device is designed for IPv6 first. Your business is slowly becoming incompatible with the future.
So what do you do? First, check if your ISP offers IPv6 on your business circuit. Most do. They just don’t enable it by default. Second, demand it. Make your ISP prove that they can’t support it. Third, test your own infrastructure. Most modern routers, firewalls, and operating systems have quietly supported IPv6 for years. You just need to turn it on. Your home network already did. Why haven’t you?
The internet is not a static thing. It evolves. And right now, the evolution is happening on the consumer side. The businesses that will win in the next decade are the ones that break free from the ‘stability’ trap and embrace the same protocol their home users already enjoy. The rest will be running 1980s infrastructure — and wondering why their competitors are faster, cheaper, and more agile.
FAQ
Q: Why would an ISP give home users IPv6 but not business users on the same fiber?
A: Because home users use ISP-provided modems that can be remotely updated and configured, while business customers often have their own routers and firewalls that the ISP doesn't control. ISPs are afraid that enabling IPv6 on business circuits will break custom configurations, causing support headaches. So they default to the 'safe' option: IPv4.
Q: Does IPv6 actually matter for my business?
A: Yes. IPv4 address space is exhausted. ISPs are increasingly using Carrier-Grade NAT (CGNAT) for IPv4, which breaks any service that requires a direct inbound connection — VPNs, remote access, security cameras, VoIP. IPv6 eliminates NAT and gives each device a unique public address. As more cloud services, APIs, and IoT devices go IPv6-only, your business will be locked out if you don't upgrade.
Q: Isn't IPv4 still 'working fine'? Why change?
A: IPv4 'works' the way a 20-year-old car works — it gets you there, but it's inefficient, costly, and soon won't be supported. The real cost is hidden: you're paying for CGNAT, for workarounds, for slower performance on modern networks. The longer you wait, the more technical debt you accumulate. Your home internet already proves IPv6 works. Your business should be at least as modern as your living room.
