IPv4 versus IPv6: Which One Should We Be Using Now? or IPv4 versus IPv6: Is It Finally Time to Make t

The real bottleneck? Legacy systems. So much old hardware and software just *can’t* handle IPv6 without expensive upgrades.

If you’re testing, try ipv6-test.com. Simple and straight to the point.

Honestly, I think we’ll only see mass adoption when IPv4 addresses become *truly* scarce and expensive. Right now, workarounds like NAT keep the lights on.

My home lab is all IPv6, though. Once you go dual-stack, you never go back.
