  IPv6-Only

• For three months, one VLAN at home had no IPv4. These are my notes on what that was like.

  The setup

  The firewall ran NAT64 and DNS64, so IPv6-only clients could still reach IPv4-only sites through translation.

  What worked

  Browsers, streaming, phones, laptops, and most apps. It was boring, which is exactly the point of a good transition.

  What broke

  Game consoles, an older printer, a few VPN clients, and anything that hard-codes an IPv4 address. Each had a workaround, but only after some digging.

  I'd do it again. The details are on the IPv6-Only Test Network project page.

Thanks for reading.
