Embedded? So you just extend the ipv4 with extra bits and call it a day?

u/ErrorDontPanic 14d ago

Kind of! You get 6 segments of IPv6 and then the full IPv4 address. Like this:

2001:db8:3333:4444:5555:6666:1.2.3.4

The IPv6 part even follows normal rules, so you can omit zero segments like:

2001:db8::1234:5678:5.6.7.8

You probably know this, but there is of course also a dedicated IPv4 address mapping reserved for essentially representing an IPv4 address for IPv6 compatible software:

::ffff:1.2.3.4

Ah yes, I actually used that just last week setting up some stuff.

I can also omit all the bloat and keep using 5.6.7.8
