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

Short answer: IPv6 is faster *in theory*. Long answer: Your ISP probably screwed it up.

Test with Pathping (Windows) or mtr (Linux) to compare routes. If IPv6’s got fewer hops and lower latency, congrats—you’ve got a good ISP.

And no, the address space doesn’t matter for speed. It’s just hype unless you’re running out of IPv4 addresses (which, tbh, some folks are).
