Which is faster in real-world use: IPv6 or IPv4? What is fast IPv6 or IPv4? Alternatively: What is fa

IPv6 *can* be faster, but it’s not a magic bullet. The real advantage? No more NAT garbage. That alone reduces latency in some cases.

But if your ISP’s IPv6 routes suck (common with smaller ISPs), IPv4 might still win. Tools like Traceroute (with -6 for IPv6) can show you the hops and where delays happen.

And no, the address space size doesn’t affect speed—it’s about scalability. Stop overthinking it.
