Thank you for this on SLAAC vs DHCP of reg. refreshing lifetime.

Just modified it, to DHCP when dhcpv6 started years that only SLAAC
configurable to IPv6 time...


Recent inquirying to local ISP how:

Modem---- R2 (wire+wireless.Node) with no setting opt for home user device
at exp. /lifetime, it auto ipcfg was 1D lease while meantime ,
modem....would displayed lease 1 hour due to R2 net suddenly invalid?!


Moden----R1 (wire. DHCP wan set replaced SLAAC, see going) ----R2
                                  |
                                  ----pc1
                                  |
                                  ---pc2
                                  |
                                   ---R0



By the way, 2002:c058:.... that ever ISP test dhcpv6 shown unknown by host
detector hyperlinks...., Is DHCP v6 expired or deleted from public register
such IANA , or it performing in privacy DNS just?
