IPv6 has been "the future of the internet" for longer than some developers have been employed. Your site probably runs fine on IPv4 today. Clients still ask whether they need IPv6 on their hosting plan, usually right after reading a blog post that sounds urgent.
Short answer for most Canadian business websites: not yet critical, often nice to have, and increasingly easy to enable when your host and CDN support it. Long answer below, without the panic.
Quick refresher: IPv4 vs IPv6
IPv4 addresses look like 203.0.113.42. There are not enough of them left for every device on earth to get a unique public address, so NAT, shared hosting, and cloud networking paper over the shortage.
IPv6 addresses are longer (2001:db8::1 style), plentiful, and designed for a world where everything connects directly. Modern networks run dual stack: both IPv4 and IPv6 when possible.
Why your site still works on IPv4 alone
Almost all visitor traffic reaches websites through paths that still speak IPv4 end to end, or translate somewhere along the way. Your hosting panel gives you an IPv4 address. DNS A record points to it. Browsers connect. Done.
Shared hosting, reverse proxies, and CDNs absorb a lot of complexity. Visitors on IPv6-only mobile networks often hit a CDN edge that talks IPv4 to your origin anyway. You would not know unless you looked at analytics by protocol.
When IPv6 actually matters
- IPv6-only users: Some mobile carriers and corporate networks prefer IPv6. Without an AAAA record, those users rely on translation layers that can add latency or fail in edge cases.
- Your own APIs and integrations: If partners require IPv6 connectivity for server-to-server calls, you need it on the endpoint they hit.
- Compliance or RFP checkboxes: Government or enterprise tenders sometimes ask if you support IPv6. "We can enable it on request" is a valid answer if true.
- Future-proofing DNS: Adding AAAA records early avoids a rushed change later when IPv4-only feels dated on an audit form.
For a typical WordPress marketing site with modest traffic, none of these are emergencies on their own.
What enabling IPv6 involves
It is not just a toggle in cPanel labeled "enable IPv6" (though sometimes it is that simple). You need:
- An IPv6 address assigned to your server or load balancer
- AAAA DNS records pointing your hostname to that address
- Firewall rules that allow IPv6 on ports 80 and 443 (and whatever else you expose)
- TLS certificates that cover the hostname (most modern issuers handle IPv6 validation fine)
- Application config that listens on both stacks if you run custom services
Miss the firewall step and you get mysterious "site works for me" reports from IPv6 users only.
CDNs and dual stack
If you front the site with Cloudflare, Fastly, or similar, they often provide IPv6 at the edge automatically. Your origin might stay IPv4-only while visitors connect over IPv6 to the CDN. That satisfies many real-world goals without renumbering your VPS.
Check what your CDN dashboard says about IPv6 compatibility before you reconfigure the origin. Half the job may already be done.
Email is still mostly an IPv4 conversation
MX records and mail deliverability revolve around IPv4 reputation, PTR records, and SPF/DKIM/DMARC. IPv6 for outbound SMTP exists but is not where most small business mail problems live.
Do not conflate "we need IPv6 for our website" with "our Outlook is broken." Different systems, different fixes.
Testing without breaking production
Before you announce IPv6 support:
- Add the AAAA record with a low TTL first
- Test from an IPv6-only network (some online tools simulate this)
- Verify HTTPS loads and forms submit
- Watch error logs for connection refused on [::]:443
Dual stack means both A and AAAA records coexist. Removing IPv4 is not the goal for most businesses this decade.
Canadian hosting angle
Canadian data residency is about where servers sit, not which IP version they use. An Edmonton VPS can have both IPv4 and IPv6. Ask your host which address blocks they assign and whether IPv6 costs extra. On many plans it is included; on some legacy shared stacks it is still unavailable.
Do you need it yet?
Probably not urgently if your site is a standard brochure or WooCommerce store on managed hosting, you are not seeing IPv6-related support tickets, and no contract mandates it.
Worth enabling when your host offers it cleanly, your CDN expects it, or you are rebuilding DNS anyway during a migration.
Prioritize other work first if TLS is expiring, backups are untested, or PHP is past EOL. Those hurt you this month. Missing AAAA records usually do not.
Bottom line
IPv6 is real, growing, and good to plan for. It is not a crisis for most small and mid-size websites still humming along on IPv4. Enable dual stack when your infrastructure makes it easy, test it properly, and do not let FOMO drive a Tuesday night DNS change.
