Nit: DHCPv6 can be (and usually is) dynamic, but it doesn't have to

like that all the time.]
Counter Nit: That's still acquiring an address via /Dynamic/ Host
Configuration Protocol (v6). It /is/ a /dynamic/ process.
Static IP address has some very specific meaning when it comes to
configuring TCP/IP stacks. Specifically that you enter the address to
be used, and it doesn't change until someone changes it in the
configuration.
Either an IP address is statically entered -or- it's dynamic.
The fact that it's returning the same, possibly predictable, address is
independent of the fact that it's a /dynamic/ process.
Counter counter nit: You may be *acquiring* it dynamically, but you can
enter the address to be used into DHCP, and then it doesn't change until
someone changes it in the configuration.
That was my IPv4 in the Demon days - DHCP was *guaranteed* to *always*
return the same address. So either I retrieved it via DHCP from Demon,
or I hard coded it into my computer, it didn't matter.
