These would be "static" in the sense of "no privacy address auto-generated
and auto-rotated(!) after a certain time by the host itself".
Phrased differently, "temporary" addresses in the sense of this discussion
(and where you want a distinction between a "NFS client" and a "web browser")
arte those generated according to RFC4914 (or 3041):
4941 Privacy Extensions for Stateless Address Autoconfiguration in
IPv6. T. Narten, R. Draves, S. Krishnan. September 2007. (Format:
TXT=56699 bytes) (Obsoletes RFC3041) (Status: DRAFT STANDARD)
USENET is *not* the non-clickable part of WWW!
